[What is physical sunscreen? 】
Physical sunscreens usually use titanium dioxide and zinc oxide as sunscreen agents. The principle of physical sunscreen is to reflect, scatter and refract ultraviolet rays through the components of solid particles. Physical sunscreen is more stable and therefore less likely to be absorbed by the skin, making it suitable for sensitive skin or young children. On the contrary, chemical sunscreen is easily absorbed by the skin, so it increases the chance of acne and even causes skin allergies.
