The main difference between face sunscreen and body sunscreen is stretchability. In order to have the effect of makeup base, facial sunscreen is the kind that is easy to apply evenly in a small area and make the skin look more delicate.

Sunscreen for the body is a type that is easy to blend with the skin, because it has a wider range of applications and greater elasticity. If you use facial sunscreen on your body, it is not easy to apply it evenly on a large scale because of its low extensibility. Therefore, it is necessary to distinguish between sunscreen used on the face and sunscreen used on the body.

The skin characteristics of the body and face are also different. Relatively difficult to get oil, the stratum corneum is thick, it is not easy to block pores, and it is not easy to be allergic than the face. Usually, the sunscreen used for the body will be refreshing, or the texture is relatively thin, and the proportion of water and milk is relatively large, which is convenient for the body to apply on a large area. Some sunscreen products on the face will add a touch-up or a formula similar to the foundation effect to help modify the small flaws on the face.

Points that must be paid attention to in sun protection:

1, choose the right 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 are particular about 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. ?

5, the amount is too small to prevent sun exposure.

Pay attention to wearing sunscreen. Take the sunscreen the size of broad beans and put it on your palm, evenly spread it and pat it on your face. Direct application is easy to cause pore blockage, and it is not easy to apply evenly. If the amount is not enough, it will also affect the sunscreen effect. Moreover, it is often not enough to apply sunscreen only once, unless you go out for a short time. Generally speaking, chemical sunscreen should be replenished every 2~3 hours, and physical sunscreen should be replenished every 3~4 hours. It is best not to expose skin for more than half an hour. ?
