1. As we all know, many physical and chemical sunscreens will turn your skin white right after application. It is no exaggeration to say that many of them are whiter than geishas at the beginning, especially those products with high powder content. It doesn’t matter. After waiting for 10-15 minutes, there will be a certain degree of improvement.

2. There will be some oiliness right after application, but the situation will be greatly improved after the components that need to evaporate evaporate. So the best advice is to wait for 10 minutes after wiping. If you are in a hurry, you can blow on your face with gentle wind before proceeding to the next adjustment. Because sunscreen can only protect our skin in all directions if it forms a film on the skin! If you put on makeup without sunscreen forming a film, the first direct impact is that it may rub mud! Secondly, sunscreen can be easily washed away by sweat, causing spots! It's like applying it in vain!

3. After the sunscreen forms a film and evaporates, applying a layer of loose powder will achieve twice the result with half the effort. The loose powder here is mainly used to adjust the skin tone. For example, darker loose powder can neutralize the whiter sunscreen, and then strengthen this protective film to set the makeup, allowing it to stay on the face longer.

Okay, that’s all about the film formation of sunscreen. I think you all understand it.
