SKIN CARE FOR OIL, SENSITIVE, DIGHT, TURRY SKIN: OSPT
SKIN TYPE OSPT
“Oily skin is very annoying. Knowing that sunscreens and skin-whitening products will help reduce dark spots, but it's hard to find products that don't leave the face shiny or irritated."
– ABOUT YOUR SKIN
If of type skin OSPT, the characteristic elements of your skin will combine to create a vicious cycle of dark spots, redness on the face. Some people have acne, others have dark spots, and people with the OSPT skin type have both. You feel suffocated because you always have to fight acne or dark spots. There is no single solution to a problem that can improve the overall skin condition. You need to be knowledgeable and solve all the problems.
Pigmentation, sensitivity and oiliness are the three dominant factors. This chapter will show how each of these factors affects your skin, and then show you how they interact with each other. Your skin is a complex skin type where a vicious cycle of problems interacts and spawns. But don't worry, you can step in and solve those problems.
Note: WHAT ACNE TREATMENT IS YOUR SKIN GOOD?
– PROBLEM ONE BY ONE
Start with oil, your biggest concern. Oily skin can lead to acne, especially in your teens (13-17) to 20s, and continues into your 30s, maybe longer. While many people expect acne to go away after puberty, for people with the OSPT type, that won't happen.
You may also find that your pigmented skin produces dark spots, dark spots, and melasma on your cheeks.
It appears a lot when you are in your 20s and 30s. Why? Because at this age, many women are pregnant or taking birth control pills, leading to abnormal changes in female hormones, which will stimulate the skin to produce oil and pigment.
Certain birth control pills can help improve acne because they reduce oil secretion but increase pigmentation and make melasma worse by affecting female hormones.
Caucasian OSPTs may be suitable for this drug, but colored OSPTs may develop unwanted pigmentation. However, symptoms of dyspigmentation that are aggravated by changes in hormone levels will pass with time.
Tackle your challenges or let them go bad? If you have acne, rosacea or allergies, treatment is necessary.
You can reduce the combination of three characteristics: oiliness, sensitivity and pigmentation by following the instructions.
If you take action to prevent acne and dark spots, you will find that you have successfully controlled your skin. Fortunately, many women with the OSPT type find their skin improves after menopause as oil production and female hormone levels drop.
If you have been protecting your skin now, when you are 50, 60 years old, a beautiful skin is waiting for you. Oily skin that worries you in your youth becomes beneficial as you age, as it helps maintain skin's moisture levels.
In middle age, with very few wrinkles, reduced oil production, and a tendency to reduce the formation of dark spots, you will have skin that resists aging better than many other skin types. When people of other skin types have to use anti-wrinkle creams (or anti-aging treatments), your skin is perfected by the benefits of oil and tight skin over time.

– COLOR
The second challenge is pigmentation. High levels of the pigment melanin can lead to a sudden appearance of ugly dark spots that do not fade for weeks or even months. Pigment-producing cells in the skin can produce various types of dark spots
Depending on your skin color and race, you will have some form of pigmentation and others will not.
Therefore, in this chapter on the best treatments for each type of pigmentation.
Dark spots develop from many factors, including: inflammation, trauma, cuts to the skin, and increased levels of the female hormone estrogen.
In addition, sun exposure causes the skin to increase the production of the pigment melanin, creating dark spots, melasma, freckles, and hereditary freckles.

– CHALLENGE OF YOUR OWN SKIN TYPE
First, congenital oily skin leads to acne ‒ which is a form of inflammation. Next, inflammation will increase pigmentation, creating ugly dark spots at the previous acne site.
These problems one after another are frustrating. Your first problem was either acne, cuts in the skin, rashes or allergies… You breathed a sigh of relief when it finally cleared up, but immediately you were battling the dark spots again. You may be afraid that these dark spots will last forever, people often refer to them as "scars". But these dark spots are not permanent and they are not scars either. By fighting inflammation, you can interfere with this pathological cycle.

– OSPT AND INFECTION
The third factor in the challenges of skin care is sensitivity ‒ which makes your skin prone to inflammation that leads to dark spots. Therefore, it is crucial to identify and avoid inflammatory triggers.
Inflammation is caused by the proliferation of blood cells (red blood cells, white blood cells) at the injured site to heal the wound. Acne, burns, insect bites, bruises, rosacea and allergies are common forms of inflammatory lesions, and any form of inflammation can produce dark spots.
Any heat source outside the body can increase the inflammatory response in the body.
Heat outside contributes to inflammation. So burns, hot waxes, sunburn, and ingredients in skin care products that irritate the skin causing redness in people with OSPT can lead to a vicious cycle: inflammation produces dark spots.
Sunbathing or burning yourself on a hot day can also produce inflammation. Although in people with OSPT skin, the pigmentation feature of the skin can prevent the skin from sunburn, the heat from the sun is still an issue.
Avoid sun exposure, hot weather, burns or sources of excessive heat from all sources. Services such as waxing, steaming, peeling or other treatments that heat or irritate the skin can promote an inflammatory response.
Note: The most effective and safe way to treat blackheads
- Plucking facial hair with tweezers can cause skin injury
- Chemical substances that cause hair loss like Nair often contain strong chemical ingredients that can irritate and irritate the skin
- Hot wax causes hair loss (hot wax) can cause inflammation
- Chemical peels are too deep to cause skin inflammation.
- The razor promises a very clean shave that increases the risk of ingrown hairs into the skin (the phenomenon of hair not growing up to the surface of the skin as usual), causing dermatitis
- Hot, spicy foods and drinks can cause inflammation
- Steam baths, thermal tights (which help with weight loss), or hair treatments that involve hot heat or harsh chemicals can cause this problem.
– SENSITIVE SKIN AND OSPT
As a sensitive skin type, you are more likely to experience redness, heat, numbness, rashes or allergic reactions when you are irritated with the ingredients in your skin care products. Most people, including skin care professionals, don't know exactly which ingredients cause irritation or inflammation, so it's your responsibility to know how to protect your skin when using skin care products. or therapies.
Even products labeled "allergen-free" can still contain fragrances or preservatives, ingredients that cause irritation to your skin. sensitive skin. Later in this chapter, we'll tell you what ingredients can cause irritation and direct you to skin care products and ingredients that are soothing, not irritating or inflammatory.
In addition to the risk of irritation with the product, it is possible that your skin is also irritated by other things from the outside environment. While this topic is beyond the scope of the book, it's not uncommon for people to have allergies to foods, fabrics, or chemicals found in clothing, furniture, or buildings.

– A CLOSE OF YOUR SKIN
OSPT skin type is quite common among people of color such as Americans, Caribbean, Latin American, Asian and Mediterranean. Caucasians such as Britons and Irish may have OSPT skin with red hair and freckles, which is a form of pigmentation.
If the questionnaire indicates that you have OSPT skin type but you do not have all of the following mentioned symptoms then your test results are not wrong.
OSPT suffers from many general problems but also has some specific problems. Thus, many of the symptoms, predispositions, and treatment options are specific to black, colored, and white OSPT.
* All OSPT may have the following symptoms:
- Acne, erythema, skin allergy
- Black spots, dark spots in sun-exposed skin
- Glossy skin when using sunscreen products
- Numbness or irritation when using skin care products
* With Black OSPT, you can get:
- Dark spots on skin that has been previously acne, irritated, or traumatized (cut, shaved, burned)
- Sunscreen looks white and purple when applied to the skin
- Hard to find the right foundation color for your sensitive skin to tolerate
- Must wear makeup to cover dark spots that cause oil, shine or acne
- Hair grows back into the skin and causes dark spots
- Dark circles under eyes
Note: How to defeat the "enemy" named acne bran
* OSPTs of color such as Italians, Indians, Latinos, Asians, or other races may suffer from:
- Oil, shine or acne when using makeup to cover dark spots
- Dark circles under eyes
Caucasian OSPT may have:
- Hereditary freckles
- Sunburn (sunspots) on hands, arms and legs
- There is a high risk of melanoma, especially if you have red hair or hereditary freckles.
Finding a suitable treatment for people with Caucasian OSPT skin type is easier because hereditary freckles and sun spots will improve more easily. They can be prevented and disappeared by avoiding the sun, using sunscreen products, combined with a skin care and treatment regimen. Skin bleaches (skin lighteners) are helpful for all OSPTs, however more intense methods such as laser and light treatments may be used by Caucasians.
If you're Asian, be cautious because even though your skin looks relatively light, there may be an inflammatory response similar to that of black people. Therefore, Asians should follow treatment advice for black or colored OSPT skin types.
OSPT fair skinned skin has a high risk of melanoma, especially if you have red hair or a history of sunburn. Take a look at the moles yourself and see a dermatologist for an examination.
– SIGNS OF SKIN CANCER
- A: Symmetry: one side of the mole is not symmetrical with the other.
- B: Contour: the contour is not clear, it is difficult to tell where the mole begins and ends.
- C: Color: Moles have many colors: white, black, red, yellow.
- D: Diameter: more than 6mm
There is no way to prevent melanoma, although you can reduce your risk by avoiding sun exposure.
It is best to be able to detect it early, while it is curable. If you notice a suspicious mole, see a dermatologist immediately. That could save your life. Wait one more day, things might be different.

– TIPS FOR OSPT SKIN
You can prevent acne, redness, and rashes by using these products. This is as risky as walking on a tightrope, while avoiding harsh ingredients while being effective in reducing oil secretion and fighting inflammation.
Second, sun exposure increases pigmentation, so use sunscreen regularly.
Third, manage stress and avoid any skin care activities and cosmetic interventions that cause inflammation. Following the steps below can change everything.
The good news is that most of your major skin problems are preventable.
Note: Prevention is key. Reduce skin irritation and pigmentation by consistently implementing an appropriate anti-inflammatory and prevention strategy.
Note: Correct understanding of eel acne
– DAILY SKIN CARE
Depending on where you are in the circle of inflammation ‒ acne ‒ black spots, choose a suitable treatment method accordingly.
Skin lighteners and oil-based products can control the typical symptoms of OSPT to a large extent.
Most of these symptoms are caused by pigmentation disorders and excessive oil secretion.
See if your skin is oily or combination to know whether to use or skip products like toners and moisturizer.
Make it a habit to use products every day to prevent your essential skin problems. You can add supportive therapies to address specific problems.
1. DAILY SKIN CARE MODE FOR PERSONS WITH ACCIDENTS AND DARK POINTS BUT NO RED SKIN
In the morning, you should wash your face with a cleanser containing salicylic acid or benzoyl peroxide, then apply a toner if your skin is very oily (if it's less oily, you can skip this step). If dark spots appear, apply a skin-lightening gel to them. If you're at risk for acne or are suffering from breakouts, apply a gel containing benzoyl peroxide directly to those areas. You can use the acne product several times a day. Apply eye cream if you want.
Next, apply sunscreen (required) and makeup (if desired).
In the evening, follow the same skin care regimen as in the morning but skip applying the benzoyl peroxide gel and sunscreen; At the same time, add an eye cream and moisturizer if needed. To determine the right moisturizer for you, read the tips and recommendations below.
Note: How to treat hormonal acne for men
2. DAILY SKIN CARE MODE FOR PEOPLE WITH RED SKIN AND BLACKS BUT NO ACC
In the morning, wash your face with a cleanser containing ingredients that are suitable for your skin. If redness is present, use anti-inflammatory wash products. For dark spots, use a cleanser containing soy (soy) or niacinamide. If the O/D score is high (≥ 34), apply toner after washing your face. If dark spots appear, apply a skin-lightening gel on top of them. Apply eye cream if you want.
Next, apply sunscreen. If your O/D score is < 34, apply moisturizer or foundation with sunscreen. If the O/D score is > 34, skip the moisturizer and just apply a sunscreen or powder that contains sunscreen.
In the evening, follow the same care regimen as in the morning, skipping sunscreen and makeup. You can apply eye cream and moisturizer if needed.
3. DAILY SKIN CARE MODE FOR PERSONS WITH RED SKIN, BLACK STICKERS AND CANCER
In the morning, wash your face with a cleanser containing salicylic acid or anti-inflammatory agents. When dark spots appear, apply whitening gel on them. If you have acne or breakouts, apply acne products to the area and carry them with you if you need to reapply several times a day. Next, apply sunscreen and makeup if desired.
In the evening, follow the same skin care regimen as in the morning, skipping the sunscreen step and adding a moisturizer if needed.
Note: How to treat blackheads for men
- Cleanser (Cleanser)
Choose a cleanser that doesn't irritate the skin to remove makeup without stripping the skin of its natural oils. This helps reduce or control skin sensitivity. If the cleanser you're using is drying to your skin, use it every two days, alternating with a cleanser for sensitive skin like Olay Total Effects Anti-Aging Anti Blemish Cleanser. Avoid cold creams and cream cleansers, as they are not suitable for oily skin.
For those with oily skin who want to clean their face several times a day, you can use these wipes on the go.
- Use toner
Oily skin types especially love the clean and comfortable feeling that toners provide. And if the toner contains ingredients such as anti-inflammatory, whitening, and oil-control, they will stay on the skin and promote its effects. However, if you have combination skin, avoid using toner on dry skin. If you experience redness or stinging when using a skin care product such as a moisturizer or sunscreen, skip the toner and use a gel containing anti-inflammatory ingredients. If your daily skin care regimen is too complicated, skip the toner.
- Squeeze acne
Oily skin is sensitive and prone to breakouts. Acne can leave scars if you pick or squeeze them incorrectly.
The products in your daily skin care regimen should work to prevent breakouts. You can treat acne with some of the products listed below, then let it go away naturally.
Above all, do not steam your face, use a hot towel, or place an ice cube on the pimple. All of which cause a sudden change in temperature, absolutely not for the type of skin that is prone to inflammation. Many people think sun exposure improves acne, but because acne is often worst in the summer, sun exposure doesn't help. It's best to apply a prescription medication containing salicylic acid or benzoyl peroxide directly to the papule.

- Treatment of dark spots
For dark spots, it is recommended to apply whitening products after washing your face, applying toner and before other products. Start using this product at the first signs of dark spots and keep it up until the marks disappear completely. If you already have a dark spot, you should immediately apply products to the dark spot.
- Moisturizing products
Moisturizing is not necessary or recommended for most people with OSPT skin types, as moisturizers can clog pores and increase oil. In most cases, your skin's natural oil production is enough.
However, if you have some areas of dry skin like around your eyes, cheeks, or mouth (or an O/D score around 27-35), use a moisturizer containing anti-inflammatory, acne, or dark spot ingredients. that area, or all over the face if needed.
- Eye cream
If there are dark circles under your eyes, you should use an eye cream containing vitamin K. It helps to address the blood vessel congestion that is causing these dark circles.
- Exfoliation
Using exfoliating products helps most skin types except OSPT because aggressive peeling can lead to inflammation and dark spots. If you use retinoids, you will find them peeling in a very natural way.
Note: Acne Treatment With Micro-Stimulation Technology
- BUY PRODUCT
By reading product labels to clearly identify the ingredients in them, you can broaden your choices.
Choose products that contain ingredients that are beneficial for your skin type and avoid ingredients that cause inflammation or increase oil.
Check the ingredients in shampoos, hair conditioners, bath soaps and shaving products because they can cause irritation when they come in contact with your skin.
- Sunscreen for your skin
Caucasian OSPTs avoid the sun because they know it will cause sunburn and freckles, a unique combination of oils and pigments, colored OSPTs can have a vibrant, rosy tan.
However, OSPTs with dark and colored skin should use sunscreen products to prevent sunspots from forming caused by UVA and UVB rays.
That's why it's imperative to wear sunscreen that blocks both UVA and UVB rays at all times, regardless of your skin color. Since OSPT is oily skin, gel, light lotion, and spray sunscreen products are better than creams or lotions. OSPT is sensitive skin, so physical sunscreens containing titanium dioxide (TiO2) and zinc oxide (ZnO) are better than chemical sunscreens (chemical sunscreens can cause skin heat and numbness). You'll still find yourself lightly tanned, as no sunscreen blocks 100% of the sun's rays.
And remember, if your skin shows a lot of melasma or freckles, avoiding the sun completely is the best way. To enhance the effect, choose products that contain both anti-inflammatory, whitening and sunscreen ingredients at the same time.
Note: How Many Times A Week Is Best For Skin
- Make up
You can cover blemishes, dark spots, or redness with makeup that contains key ingredients to help prevent those problems.
For acne control, look for products with Salicylic acid (like Neutrogena Skin-Clearing Oil-Free Makeup) that improve skin, increase flaking, and reduce oil.
To prevent dark spots, look for a foundation with sun protection. There are three lines of foundations: oil-based, oil-free, and containing some additional ingredients (sunscreens, for example).
The best oil-free line for your skin. Or you can skip the foundation step, instead using a powder containing sunscreen ingredients.
Darker-skinned OSPT people need to find foundation products with darker shades. Iman Cosmetics (available from Walgreens and Target) specializes in colored foundations, choose an oil-free product that works for you.
Oil-control powder will help reduce the shine of the skin when other oil-control lotions or gels are not very effective. Moreover, products containing sunscreen will protect the skin from ultraviolet rays that stimulate the formation of pigmentation.
– TREATMENTS FOR YOUR SKIN
In most cases, products applied directly to the skin provide the best results for black OSPT people. Treatments are often unnecessary and sometimes even harmful. However, you need to be patient when applying the products because it takes a while for a noticeable change.
Black OSPT people should avoid phototherapy, as it can cause inflammation and make dark spots worse. The only therapy that works is blue light therapy, which kills bacteria and helps treat acne. You need treatment one to two times per week, for six weeks.
If your skin is fair or colored, you can opt for IPL treatment. White OSPT people have less inflammation than black OSPT people, so IPL and other light treatments are more effective, helping them remove dark spots quickly. In addition, they may also use blue light therapy to treat acne.
– Additional options
Black people or those who do not want (or cannot use) IPL can use a chemical peel. Look for peels that contain 20-30% salicylic acid (BHA), which will remove the outermost layer of skin and promote cell renewal, thereby improving dark spots.
* SUMMARY, HOW TO HAVE A HEALTHY SKIN IS:
1. Pay attention to the pH of all skincare products you are using – say NO to products with a pH above 7, especially cleansers.
2. Use an acidic toner (pH 3.5-4.5) to balance the skin after washing your face (because tap water in Vietnam has a pH of 7).
3. Do not wash your face with cleanser more than 2 times / day, do not exfoliate more than 2 times / week, do not use a towel that is too rough and hard to avoid damaging the skin barrier.
4. Protect your skin from UV rays every day by using the right sunscreen
5. Give enough moisture to the skin barrier with a moisturizer that contains both Oclusives (coatings) and Humectants (desiccant)
6. Absolutely do not use quick bleaching products in a short time because they will erode and thin the skin barrier.
7. It is recommended to use more plant-based oils containing fatty acids in the daily skin care routine to strengthen the lipid film and increase the cohesion of the horny cells.
8. Do not use water that is too cold or too hot, do not soak the skin in water for too long to limit dehydration of the skin.
9. Regularly supply more water by spraying minerals, applying lotion mask, applying skin care masks.
10. Eat healthy, avoid stimulants, avoid pollution, dust.
SUNSCREEN
1- There's No Reason For You Not To Use Sunscreen
Ultraviolet rays in sunlight abbreviated as UV - Ultra Violet Rays before 7 am, sunlight is beneficial for the skin, helping the skin to supplement vitamin D, develop the body.
After 7 hours, stronger UV rays will cause adverse effects on the skin: damaging the skin barrier, causing darkening, pigmentation, tanning, wrinkles, increasing skin aging time, increasing the risk of skin cancer.
=> You are required to use sunscreen when going out between the hours after 7 am and before 5 pm.
| The reason why you think that you don't need to apply KCN | The truth is… |
| Or stay indoors, work in the office, less exposed to the sun. |
UV rays can penetrate glass, reflect off walls, tables, chairs and all other objects. Electronic devices such as phones, computers, televisions also emit ultraviolet rays that adversely affect the skin. |
| Are you afraid that sunscreen will make your skin secret, oily, and cause acne? | UV rays are the main cause of acne and blackheads because it promotes oil production, leading to clogged pores. |
| Are you worried that your skin will be more sensitive because sunscreen contains many chemical ingredients? |
The skin is already weak, vulnerable to UV rays, making the skin barrier more weakened, making the skin more sensitive. There are many benign, safe, non-irritating sunscreen products. |
| If you have a sunscreen, a mask, a hat, then applying sunscreen is not necessary |
– UV rays can penetrate any fabric, thick clothes only partially block UVB but not UVA. – Clothes only have SPF5, while to create a safe protective film for the skin, SPF15 sun protection is minimum. |
| So many steps every morning: washing face, skin care, makeup, now even sunscreen. | “The road to success has no footprints of the lazy.” You want to be beautiful but you don't want to invest some time and effort, you can't achieve your goal. |

2- No Sunscreen, Then You Don't Need Skin Care
- If you do not use sunscreen daily, no matter how expensive skin care and restoration products are, it is useless.
- Just investing in skin care products without sun protection is like trying to build a beautiful wall but letting bad guys come and destroy that wall every day (you try to take care of your skin while the UV rays are in the air). The sun still destroys your skin day by day).
➔ PROTECT the wall, chase the bad guys, make the bad guys not reach your wall. That means you must use sunscreen to protect your skin every day if you want to have a beautiful young skin.
3- Meaning of Common Indexes in Sunscreen
A good sunscreen must block both UVA and UVB rays, the ability to block these rays is shown by indicators such as SPF, PA or PPD.
SPF (Sun Protection Factor)
- A rating that measures a product's protection against UVB rays.
- The higher the SPF, the longer the protection against UVB rays.
- Each SPF protects the skin for about 5-15 minutes depending on each person's skin pigmentation. However, the actual time will be reduced by about 50-60% compared to the theory due to dust, sweat, friction, clothing and water.
- In fact, no sunscreen has 100% UV protection. Sunscreen with high SPF, the ability to filter UVB rays is also higher, but from SPF30 or higher, that ability is not much different, choosing a sunscreen with too high SPF (over 50) is not necessary.
PA (Protection Factor of UVA) or PPD (Persistent Pigment Darkening)
- Measure the ability of a product to filter UVA ultraviolet rays
- Asian cosmetic companies often use PA index, European countries often use PPD index.
- The higher the PA and PPD, the higher the ability to protect the skin from UVA rays
Note: Skin Care Secrets After Burning Freckles Without Recurrence
Broad Spectrum
Many sunscreen products originating in the US and UK do not have PA, nor PPD, instead the word Broad Spectrum (broad spectrum sunscreen).
Sunscreen products with SPF greater than 15 and labeled Broad Spectrum on the package are recognized as providing comprehensive protection against both UVA and UVB.
Summary:
- You should choose a sunscreen that can block both UVA and UVB for comprehensive skin protection.
- Do not use products with a higher sun protection index than necessary because they will stick for a long time on the skin, easily causing skin irritation and irritation.
- With the tropical climate and skin color of Vietnamese people, the level of sun protection that is moderate, safe and suitable for daily use for non-pigmented skin is SPF30 to SPF35, PA++.
- If you have pigmented skin or spend a long time outside on sunny days, use a sunscreen with SPF 40 to 50, PA+++ (~PPD8) or higher.
4- Classification of Sunscreens
Many of you think that sunscreen products are classified by texture (cream, gel, milk, spray …). However, this classification is not really clear because many sunscreen products have different textures but similar effects.
For a clear distinction, sunscreen products are classified based on the active ingredient (main ingredient) and the principle of action. There are three basic types: physical industrial zones, chemical industrial zones, and chemical hybrid physical zones.
Note: Care for Dry and Sensitive Skin: Are You Making a Mistake?
Physical sunscreen
How it works: Creates a protective barrier that blocks, spreads and reflects UV rays, making them impossible to penetrate the skin. The cream lies on the surface of the skin like a coat, a wall capable of reflecting ultraviolet rays.
Main ingredients: Zinc oxide, Titanium dioxide.
Advantage:
- Because it only covers the outside but does not penetrate the skin, the physical IP is very benign and safe for the skin
- Sustainable under the sun
- Effective immediately after application without waiting.
Disadvantages:
- Thick and a little hard to spread.
- Leaves a white film on the face, causing a bit of a feeling of mystery and easily causing greasy shine.
- Currently, with modern cosmetic technology, new generation physical sunscreens with ingredients composed of microparticles have partly improved the above weakness.
Skin type to use:
- Sensitive skin, easily irritated
- Dry skin
- Acne skin
For example:
- Elta MD UV Physical SPF 41
- Innisfree Extreme Safety 100 Sun Cream SPF50+
- The Face Shop Natural Sun Eco Power Long-lasting Sun Cream SPF50+
Chemical sunscreen
Working principle: Acts as a chemical filter, by absorbing and permeating UV rays. When UV rays penetrate the skin, they will be neutralized, decomposed, and released by chemical sunscreen substances, making UV no longer have the opportunity to penetrate deep into the epidermis to cause skin damage.
Main ingredients: Octinoxate, Octisalate, Octylcrylene, Avobenzone, Oxybenzone, Sulisobenzone, Homosalate…
Advantage:
- Colorless, leaves no white film
- Absorbs quickly into the skin, does not leave the skin greasy and shiny
Disadvantages:
- May cause eye irritation if perspiration, some chemicals can be irritating to sensitive skin
- It takes about 20 minutes for the cream to absorb into the skin before going out in the sun
- Most chemical industrial zones are not stable in the sun, so they have to be reapplied after 2 hours. However, now a number of new generation chemical sunscreens have used Tinosorb sunscreen to overcome this problem.
Skin type to use:
- Oily, greasy skin
- Dry skin (if that type of chemical industrial park contains moisturizing ingredients and does not contain drying alcohol)
For example:
- Clinique Sun Broad Spectrum SPF30 Sunscreen Face Cream
- Neutrogena Ultra Sheer Dry-Touch Sunscreen SPF55
- Kiehl's Super Fluid UV Defense Broad Spectrum SPF 50+
Chemical hybrid physical sunscreen
How it works: Integrating the characteristics of both physical and chemical sunscreens, both shielding and absorbing and diffusing harmful UV rays.
Main ingredient:
- Usually contains both physical sunscreens (ZinC Oxide, Titanium Oxide) and chemical sunscreens (Octocrylene, Octinoxate, Triazine, ...).
- Some new generation chemical-hybrid physical sunscreens also contain "star" active ingredients, Tinosorb S, Tinosorb M and Mexoryl SX, Mexory XL - these are organic particles that can reflect, scatter and Light-absorbing, broad-spectrum sunscreen that protects skin from both UVA and UVB rays.
Advantages: both highly aesthetic, does not cause white film streaks on the skin, does not secrete skin discomfort, is durable in the sun and does not have to be reapplied continuously.
Cons: Contains a few chemical sunscreen ingredients, so it can still cause eye irritation or skin irritation, even if it's very small.
Recommended skin type: suitable for most skin types.
5- How to Choose Sunscreen For Each Skin Type And Specific Cases
a) Sensitive, easily irritated, acne prone skin Da
- Stay away from creams that contain fragrance (fragrance), oxybenzone, alcohol, and PABA (chemical sunscreen).
- Should use physical sunscreen because of benign ingredients, less irritating to the skin
- Use products with the phrase “Non-Comedogenic” on the packaging.
b) Dry skin
- Avoid sunscreen products that contain drying alcohol
- Use a sunscreen that contains a moisturizer.
c) Oily (oily) skin
- If you do not have acne problems or your skin is not too sensitive: chemical sunscreens with light texture and fast absorption are the most suitable choice.
- If your skin is both oily and sensitive: choose one that contains the words “No Sebum” (non-greasy) or “Oil Free” (oil-free) or “Dry-touch” (dry) on the package.
- Chemical hybrid physical sunscreens are also quite suitable.
d) When going swimming
- It is necessary to use sunscreen products that are water-resistant, anti-drift, often with the words “Water Resistant” or “Water-Proof” on the package, with a sun protection factor of SPF50 and PA+++ or higher.
- After 1-2 hours, you need to reapply for the best sun protection effect.
e) Sunscreen used when applying makeup
- Chemical industrial park is thin and natural, but after a short time, it has to be reapplied, affecting the make-up layer ➔ aesthetic but inconvenient.
- Physical industrial zones can be maintained for a long time, but creating a white film that makes the base layer thick and unnatural ➔ convenient but lacking in aesthetics.
So, the most suitable sunscreen to use when wearing makeup is:
- Physical IP has a color (tinted) close to skin color such as pink, rose gold, both sunscreen and makeup primer.
- Chemical-hybrid physical industrial park (containing Tinosorb or Mexoryl) because it is both thin and light to help a natural base layer, while also being sustainable and long-lasting.
6- Use Sunscreen Correctly For Maximum Effectiveness
Apply the required amount
It is recommended to use 2mg of sunscreen per 1cm2 of skin (ie about 25-30g for the whole body and 1/4 to 1/3 teaspoon for the face), equivalent to an amount spread from the base to the fingertips between or equal to 1 coin.
A tube of 50ml sunscreen if used daily, 1-2 times a day, in about 2-3 months you will use it up, if it is longer than 3 months, it means you do not use enough dosage.
How to apply
- Dot the cream evenly on the spots on the face, pat evenly. Gently pat and press until the cream is absorbed into the skin. The "slapping" sunscreen on the skin helps the cream penetrate faster, dry and more evenly, so the skin is protected more effectively.
- If the skin does not absorb a large amount, the cream can be divided into 2 applications.
- After a few minutes, if the skin is oily, you can use blotting paper or powder.
Order of use
Lotion or moisturizer -> sunscreen -> makeup (if applicable)
Should be used in turn, each step is about 3-5 minutes apart. Do not mix moisturizer or foundation with sunscreen as this can destroy the formula of the sunscreen.
Time to apply sunscreen before going out in the sun
- Chemical sunscreen: wait 20-30 minutes (so that the sunscreen agents can absorb and skin)
- Physical sunscreen: no need to wait, after applying 2-3 minutes, you can go out immediately.
- Chemical hybrid physical sunscreen: wait 10-20 minutes.
How often should sunscreen be reapplied?
- If outdoor activities, sweat a lot or go swimming, travel: should reapply sunscreen every 3 hours
- If the working environment is indoors, in the office, sitting all day in the office, away from the sunny window and only going out in the morning and late afternoon: just apply sunscreen 1-2 times/ day is enough.
After the above article, what do you think? You have really understood your skin type right yet?
From theory to practice
Although Baumann's skin classification system is somewhat more specific and accurate in assessing skin, we should understand that this is only a systematic method from the perspective of four factors. factor, not a specific solution, is if your skin belongs to any group, you need to take care of your skin.
There are two issues to keep in mind:
• The skin on your face can have different characteristics, it is normal for the cheeks to be dry and the forehead to be oily. If the difference is small, that's okay, but if it's too big, maybe you should treat each skin area as different skin types and treat them separately.
Suppose in the above case, you can consider your cheek skin as DRNW and forehead skin as OSNT and then follow the corresponding regimen for example. The specific skin care is also reasonable to explain the spot treatment method, for example, if your skin has acne, where is it considered a special skin, only apply acne cream there. Just don't apply the whole face.
• Distinguishing skin type and skin condition: One of the dangerous mistakes of skin classification is the confusion between skin type and skin condition. Each person's skin type is fixed, but the skin condition is constantly changing depending on the environment and care.
For example, people with oily skin will have large pores and active sebum, this is a genetic factor, normal skincare will not be changed. However, in the dry winter, the person's skin becomes more balanced, even showing signs of dryness. In this case, the skin type is still fixed with the element of oily skin (Oily) but the weather fluctuations have caused the moisture on the skin's surface to change. The purpose of skincare is to overcome the disadvantages of the skin type through balancing the state of the skin. This means that even if you know your skin is oily, when the surface of your skin is dry, you need to change the appropriate moisturizing measure to bring the skin state back to balance.
