What is the difference between a physical (mineral) sunscreen and a chemical sunscreen?

  The difference between a physical (mineral) sunscreen and a chemical sunscreen comes down to their active ingredients, how they interact with your skin, and how they defend you against UV light. 1.

Step 1: The Oil-Based Cleanser: 60 Seconds (Dry Skin). Apply a cleansing oil or cleansing balm directly onto your dry face with dry hands . Massage it gently for 60 seconds. Why it works: The oil instantly breaks down and liquefies the water-resistant mineral fil...
