The so-called summer without sunscreen immediately become black charcoal! No way, no way! There are still people who don’t wear sunscreen when they go out.Now we should all go out to put on sunscreen, right, after all, do not apply sunscreen a cool, want to whitening crematorium! It is difficult to get back to white.
After all, sunscreen is a lifelong career, mainly sun is too easy to get old, how can our little fairy old! Out simply want to wrap themselves into mummies!Many little sisters must only know that sunscreen is to prevent sunlight, in fact, sunscreen is to prevent the invisible and invisible ultraviolet rays!
Ultraviolet rays are also divided into UVB, UVA, UVC these three, generally speaking, the prevention of UVA and UVB.
UVB wavelength medium, will cause sunburn and skin redness and heat pain, carcinogenicity is the strongest; UVA wavelength longer, easy to cause sun redness and sunburn, the main cause of skin aging and wrinkles.
PS: UVC wavelength is shorter, penetration is also not strong, basically will be blocked by the ozone layer, can not reach the face.
In addition to the science of UV, but also want to talk to the little sister on the sunscreen some small logo, I bet a lot of little sister certainly do not recognize ~The most common on the sunscreen is the SPF and PA logo, SPF is used to indicate the sunscreen’s UVB protection ability, that is, the skin against UVB time times.
The SPF value is different, indicating that the time of effective sun protection is also different, the larger the value after the SPF, representing the longer the time to prevent sunburn and sun redness.PA is used to indicate the UVA index of this sunscreen, represented in the sunscreen products is the level of sunscreen delay skin tanning, simply put, the strength of the sunscreen tanning protection.
Generally PA is divided into three levels PA++, PA+++, PA++++, the + behind it indicates the effect of sunscreen tanning, sun aging, + the more the stronger the ability to delay the skin tanning, sun aging for a longer time.According to the knowledge learned above, we can well according to their own needs to choose sunscreen, but there is one thing we should pay attention to! The best sunscreen also needs to be diligent!
The sunscreen on the market now is generally divided into three types: physical sunscreen, chemical sunscreen and physical and chemical hybrid sunscreen.Physical sunscreen refers to the refraction and scattering of ultraviolet rays to the surface of the skin to block the outside, when applying sunscreen, your skin is equivalent to a reflector, which can reflect the sun’s rays back.
Common physical sunscreens are titanium dioxide, zinc oxide, etc., suitable for dry skin, sensitive skin, not easy to cause allergies, but easy to whitish more thick.The principle of chemical sunscreen is to absorb UV rays and convert it into energy that can be released to achieve the effectiveness of sun protection.
Common chemical sunscreens are UVB absorbers (cinnamates, salicylates, etc.), UVA absorbers (phenyl ketones, MexorylSX, etc.).Chemical sunscreens generally have a refreshing texture, no weightiness after application, not whitish and not greasy, suitable for oily skin and oily skin. However, chemical sunscreens can be irritating to the skin and need to be reapplied.Combine the advantages of physical sunscreen and chemical sunscreen respectively, try to optimize the skin feel and effect, the need to remove makeup is mainly to see the proportion of physical sunscreen agent, more on the unloading wash.

The liquidity of the liquid is good, similar to the texture of the correction fluid, better to push away, but the hand feel greasy.There will be a boring feeling, but the film is more refreshing, not white, matte feeling, but contains alcohol content is not recommended for small sisters of sensitive skin.

The actual chemical sunscreen is usually that we need to replenish it often.
