What is the difference between mineral and chemical sunscreen?

Mineral sunscreens containing zinc oxide and titanium dioxide sit on top of the skin and physically reflect UV rays. Chemical sunscreens containing filters like avobenzone or octinoxate absorb UV radiation and convert it to heat. Mineral sunscreens are generally considered gentler and better for sensitive skin, while chemical formulas tend to be lighter and more cosmetically elegant. Both provide effective broad-spectrum protection when used correctly.
