Excerpt from Byrdie.com... 5 Skincare Items You Should Never Spend Money On
AVOID PRODUCTS WITH CHEMICAL SUNSCREEN
Chemical sunscreen is different from physical sunscreen in that it changes UV rays into heat, which then radiates off the skin, whereas physical sunscreen sits on top of the skin and deflects UV rays (think zinc oxide). However, Dr. Ceballos cautions against turning to chemical sunscreen as your first or only option. Since it's made with compounds that are actually absorbed into the skin, those with acne-prone or sensitive skin might want to stick with a physical sunscreen instead to avoid potential irritation.
