Do you need to remove sunscreen? Most people do it wrong!

In the hot summer, sun protection is a topic that beauty lovers are very concerned about. When this season comes, the sales of sunscreen will rise steadily, and people's demand for sunscreen will also increase greatly. However, many beauty lovers only pay attention to how to use sunscreen, but don't know whether sunscreen needs to be removed.

Sunscreen needs to be removed

General sunscreens can be divided into two categories according to the sunscreen: physical sunscreen and chemical sunscreen. The working principle of physical sunscreen is to rely on reflection to shield ultraviolet rays to achieve the purpose of sun protection. This is like putting a protective suit on the skin. When the sunlight hits the protective suit, it is radiated away, and the skin will not come into contact with ultraviolet rays. Physical sunscreens "lie" on the surface of the skin. Since this type of sunscreen must be stably blended with other ingredients into sunscreen, oily solvents are generally used. Therefore, physical sunscreens are relatively thick. When applied to the face, the skin turns white and has heavy particles.

Why do some people say that makeup removal is not necessary?

Chemical sunscreen absorbs ultraviolet rays in sunlight and converts them into heat energy, thus preventing ultraviolet rays from damaging the skin. The advantages of this type of sunscreen are that it has a refreshing texture, does not cast a whitening effect, is not greasy, and is suitable for all skin types, but it takes time for the skin to absorb it, and it is "not long-lasting", which is why some people say they don't need to remove sunscreen.

Physical sunscreen also needs to be removed

Physical sunscreens are absorbed on the surface of the skin and mixed with other skin care products. Simply washing your face will not clean it completely. This will affect the skin's absorption of nutrients from skin care products and block the pores from being unblocked. In addition, many sunscreens now have waterproof functions, which are difficult to clean. Therefore, physical sunscreens need to be removed.
