  • Chemical Sunscreen Vs. Physical Sunscreen Pros And Cons

    Physical sunscreen cons Chemical sunscreen contains organic (carbonbased) compounds such as oxybenzone octinoxate octisalate and avobenzone which creates a chemical reaction and works by changing UV rays into heat then releasing that heat from the skin. It is often referred to as a chemical or organic absorber.
