How to choose the right sunscreen for you
Decoding the sun protection index of sunscreen
You will see some products that say SPF (Sun Protect Factor). This is a measure of a sunscreen’s ability to protect against UVB rays. The scale used ranges from 1-100, the higher the SPF number, the longer the UVB protection time. Currently, sunscreen has the lowest SPF of 15 with 15 minutes of sun protection, the highest is 100.
Sunscreen has a PA (Protect Grade of UVA) rating that measures the protection against UVA rays in sunlight. The PA index is represented by a (+) sign. The more PA products with the (+) sign, the higher the sun protection ability.
Sunscreen with PA + has about 50% UVA protection.
PA++ is about 60-70% resistant, PA +++ will effectively block about 80%. Highest PA++++ index with protection up to 90% of UVA rays.
According to dermatologists, you should choose sunscreen products that are broad-spectrum and suitable for your skin.

Is Nano-particle sunscreen safe?
Currently, with modern production technology, many sunscreen products contain nanoparticles. So is this ingredient safe?

Thanks to that, when applying the cream, it penetrates quickly, does not cause greasy feeling, and clogs pores. Thereby, preventing the formation of acne, reducing the size of pores.
Research also shows that these nanoparticles do not penetrate the blood, so they are absolutely safe for human health. In summary, the nanoparticles do not cause harm to the user.
Dark skin using sunscreen is only harmful?
There are many people who think that only people with fair skin are susceptible to sunburn, so they need to use sunscreen. And in the case of dark skin, on the contrary, there is no problem. This is a completely wrong view. Ultraviolet rays in sunlight do not discriminate against anyone, skin type. It all invades and causes cell damage, even skin cancer.

Common chemical sunscreen ingredients include: aminobenzoic acid, octisalate, oxybenzone, octocrylene, and avobenzone. In it, there are some rumors that oxybenzone disrupts hormones. This process can be understood as the substance that penetrates through the cell gills, hindering the body’s natural hormone production. However, there is no convincing evidence that oxybenzone is harmful to human health.
The above rumors appeared not by accident. One organization did an experiment: feeding guinea pigs directly food with oxybenzone for a long time. They then noticed that the mice had changes in hormone quality.
However, in 2017, a study published in the American Journal of Dermatology “vindicated” oxybenzone. Accordingly, scientists confirmed that a person must use sunscreen with oxybenzone continuously for 277 years to be affected.
In addition, oxybenzone also exists in everyday life: paints, plastics, hairspray, nail polish… This ingredient is completely harmless to human health in a certain dose. If you are not sure, you can choose other chemical sunscreens or physical sunscreens.

As a result, the skin is allergic, damaged and may require hospital treatment. Do not be greedy for short-term benefits that affect your skin.
