For modern women sunscreen Always one of the most needed products. Because not only protects the skin against the negative effects of UV rays, but this product also works to block the effects of radiation from electronic devices very well.
However, choosing sunscreen is like choosing cosmetics, not everyone knows how to choose the right, safe and most effective product for their skin. Therefore, this article Miss Tram - Natural Beauty Center Please share important notes when choosing sunscreen.
6 Factors To Consider When Choosing Sunscreen
1. It is necessary to pay attention to the expiration date of the product
With any cosmetic, the expiry date is very important – because they will determine the quality and safety of the product.
For sunscreenThe closer to the expiration date, the less effective the UVA/UVB protection ingredients in the sunscreen will be. Therefore, you need to give priority to buying newly manufactured products.
In addition, you should also be concerned about the expiration date of your sunscreen – this is not an expiration date, but the length of time you should use it after opening the product cap. Normally, sunscreen only has a shelf life of 6-8 months - beyond this time, the nutrients in the cream will be oxidized and bacteria penetrated. Therefore, you should only choose to buy products with enough volume to use for a few months.

2. SPF is extremely important
SPF is an indicator that shows how long a product will protect against UVB rays. It can be said that the higher the SPF, the better the ability to filter and block ultraviolet rays.
However, the SPF 30 to SPF 50 is considered the most ideal level you should use on summer days. Because, with too high SPF like SPF 60, SPF 100, the sun protection is not much higher, but they have a rather heavy texture, so they make the skin easily clogged - easy to cause acne.
note, 1 SPF is equivalent to 10 minutes to limit the effects of UV rays, that is, sunscreen with SPF 30 will have 10 * 30 = 300 minutes = 5 hours of effect. But in fact, you need to "depreciate" the time using them. Because factors such as sweat, clothing, usage or external influences will reduce 30-40% of the effective time of sunscreen compared to the theory.
Therefore, with products with an SPF of 30, you should regularly reapply every 2-3 hours to ensure optimal skin protection.

3. Don't forget the PA . index
PA index stands for PFA (Protection Factor of UVA) - is an index that indicates the ability of sunscreen to protect skin from UVA rays.
Most conventional sunscreens have the ability to filter UVB rays, but not all products can protect the skin from the harmful effects of UVA rays - the cause of aging and pigmentation on the skin. Therefore, manufacturers have given the PA index to show the UVA protection of their products.
PA index has 3 levels:
- PA+: Effective against UVA rays (with the level of 40 - 50%).
- PA++: Very effective against UVA rays (with a level of 60 - 70%).
- PA+++: Highest UVA protection (with 90% or higher, up to 98%).
For optimal skin protection, you should choose sunscreen products with both SPF and PA ratings.

4. Note the water resistance of sunscreen
Currently, there are many sunscreen lines that are advertised as 100% water resistant - can be used when going to the beach, swimming without worrying about getting sunburned.
However, the reality is that no product can be 100% waterproof. But, products labeled Waterproof will also have a long-lasting effect, waterproof when sweating or in contact with water. Therefore, depending on the purpose and environment of use, you can still choose a sunscreen line with or without water resistance.

5. EWG Verified
According to EWG - American Environmental Monitoring Organization, many sunscreen lines today have ingredients that are not safe for human health. Because many harmful ingredients are still included in the product by manufacturers at “acceptable levels” – and this still carries the risk of harming the body. Therefore, if you want to use sunscreen safely, you should choose products with the EWG Verified symbol.
6. Stay away from harmful ingredients
There are two main types of sunscreen products, which are physical sunscreens and chemical sunscreens:
- Physical sunscreens have the effect of emitting and emitting UVA/UVB rays to protect the skin.
- Chemical sunscreens will absorb UV rays to decompose and treat before they penetrate and cause damage to the skin.
Depending on your preferences and "wallet thickness", you will choose a product that is right for you. However, be careful to stay away from these 7 harmful ingredients: Oxybenzone, Octinoxate, Fragrance, Parabens (butyl, ethyl, methyl, propyl), Octocrylene, Retinyl Palmitate, Homosalate. These are ingredients that EWG has recommended as having an effect on users' health.
