Top 10 sun protection for face and skin

Sunscreen is the most important part of skin protection. Sunscreen should not only prevent tanning but mainly prevent ultraviolet rays. Ultraviolet rays not only accelerate the formation of skin melanin, sunburn, and even cause “skin cancer.” It also attacks the collagen fibres of the dermis, reduces the elasticity of the skin, and accelerates the ageing of the skin. In addition, “photoaging” is also the main reason for the ageing of our skin.

Ultraviolet rays are referred to as UV, including UVA and UVB, which are the biggest killers that harm our skin. UVA is the culprit of tanning and ageing. It can directly penetrate the skin and reach the dermis layer, accelerating the production of melanin and the speed of skin ageing. UVB is the culprit of sunburn and sunburn. The penetrating power is relatively weak, but its energy is large, and it can cause visible damage to the naked eye in a short time.

SPF is the time intensity of anti-UVB, which refers to the ability to prolong the time of sunburn. The larger the value, the longer the time you get sunburned.

PA is the index of anti-UVA. It refers to the ability to prolong the time of tanning. The more “+” signs, the longer you can be tanning.

In layman’s terms, SPF refers to the sunburn index and sunburn index. The higher the index, the better the effect; PA is the length of time to protect against tanning. A + represents four hours. For example, PA +++ means 12 hours of sunscreen.
