Is physical sunscreen better for sensitive skin than chemical sunscreen?

Yes. Physical (mineral) sunscreen is almost always better for sensitive skin because chemical sunscreens absorb into skin and convert UV rays into heat, which can trigger irritation. Zinc oxide and titanium dioxide sit on top and reflect UV away, reducing the chance of a reaction. The trade-off is thickness or white cast, but newer formulas are better. If your skin is cranky, skip the chemical stuff.
