What does sunscreen film formation mean?

Sunscreen film formation refers to the fact that after using sunscreen, when girls look in the mirror, they will find that the surface of their skin looks shiny, as if there is a layer of film, and it will feel a little slippery when touched with their hands. This refers to the film formation of sunscreen.

What is the role of sunscreen film

First of all, if the sunscreen forms a film, girls will feel that there is a thin film on the surface of their skin, which can better protect against the damage of ultraviolet rays. In fact, the better the film-forming effect of the sunscreen, the better its waterproofness. Girls can apply a proper amount of sunscreen on the back of their hands, and then splash clean water on the back of their hands. They will find that the sunscreen with a good film-forming effect will generally condense on the back of their hands in the form of water droplets after splashing water. If the film-forming effect is poor, it is possible that it will be directly dissolved in water, and its waterproof property will definitely be poor.
