The first new American sunscreen filter in a generation stopped being a proposal on June 10 and became a rule. That is genuinely good news, and…

Unscented usually describes what your nose notices. Fragrance-free is supposed to describe whether added fragrance ingredients are present. Neither phrase is a universal sensitive-skin guarantee.
Sep 3, 2026 · Routines & Ingredients
Four acids, three of them cosmetics and one of them a drug. Which lane it sits in tells you more about what it can claim than…
