2, sunscreen ingredients
Sun protection is divided into physical sun protection and chemical sun protection:
1. The tiny particles in physical sunscreen are generally composed of titanium dioxide and zinc oxide.
2. Chemical sunscreen, salicylate, cinnamate and anthranilate are considered as safe and non-irritating sunscreen ingredients.
How sunscreen works:
1, physical sun protection
Use sunscreen particles to form a protective layer on the skin surface, reflecting light waves that may harm the skin in ultraviolet rays, thus protecting the skin. Physical sunscreen particles generally stay on the skin surface and will not be absorbed by the skin, so the burden on the skin is relatively small and it is not easy to cause skin sensitivity.
2. Chemical sunscreen
Through the combination of some chemicals and cells, before the cells are damaged, the parts of ultraviolet rays that may harm the skin are absorbed first, so as to achieve the purpose of sun protection.
3. How to use it
1. Choose a suitable time before going out. When the weather is clear in summer, the period with the strongest ultraviolet rays is from 10 to 16 every day. Try to avoid long-term outdoor work or physical exercise during this period. If you have to go out, you should take sun protection measures, such as playing with a parasol, wearing a hat, wearing sun protection clothes and applying sunscreen. Before applying sunscreen, apply a little sunscreen product on the inside of the arm and other places to observe whether the skin is allergic, and then apply it to the whole face and body to make sure it is not allergic.
2. Sunscreen can be divided into physical and chemical types. The main components of physical sunscreen are titanium dioxide and zinc oxide, which can form a protective film on the skin so that ultraviolet rays cannot penetrate the skin surface. Physical sunscreen is a white paste, which takes effect immediately after application and has little irritation to the skin. However, its touch-up effect is unnatural and moist, and it is not suitable for full-body sun protection. Makeup remover must be used to assist makeup removal. Chemical components in chemical sunscreen cream, such as p-aminobenzoic acid and its derivatives, cinnamic acid, etc. It can absorb ultraviolet rays and convert them into other energy for sun protection. Apply chemical sunscreen half an hour before going out, so as to have a sunscreen effect.
3. Special people should pay attention to sun protection. Although physical sunscreen is better than chemical sunscreen, most of them are the combination of physical sunscreen and chemical sunscreen on the market. In summer, it is recommended to choose sunscreen with high SPF, such as SPF30+ products that can protect both UVB (medium ultraviolet) and UVA (long ultraviolet). Physical sun protection is most suitable for people with sensitive skin, the elderly and pregnant women. Children's skin is delicate, so it's best to use special sunscreen for children. Choose waterproof sunscreen when swimming, diving or sweating heavily.
4. Moisturize before applying sunscreen. Regular cleaning and skin care should be carried out before applying sunscreen, and moisturizing cream must be used before applying sunscreen to promote skin repair.
