K-Beauty Sunscreen Culture: Why Korea Treats SPF Like a Lifestyle
Daily reapplication, cushion compacts, and PA ratings as the norm.
The FDA has not added a new sunscreen filter to the monograph since 1996 (until 2026's bemotrizinol).
Dr. Ellen Marmur notes the U.S. lags because filters here are regulated as drugs, not cosmetics.
Frequently asked questions
Why are European and Asian sunscreens different from American ones?
The US regulates sunscreens as OTC drugs, so adding a filter requires drug-level safety data and FDA approval — a slow process that stalled for decades. The EU, Japan and Korea treat them as cosmetics or quasi-drugs and approve modern filters faster, which is why foreign formulas often feel lighter and cover more of the UVA range.
Why can't I buy some foreign sunscreens in the US?
Sunscreens sold in the US may use only FDA-approved filters and must meet OTC-drug rules, so a foreign product containing filters the FDA hasn't cleared (e.g., Tinosorb M or Uvinul filters) can't be legally marketed as sunscreen here. You may see them sold abroad or, unreliably, via personal import.
What does PA++++ mean on a sunscreen?
PA is the 'Protection Grade of UVA,' a rating developed in Japan and used across Asia, based on the Persistent Pigment Darkening (PPD) test. It runs from PA+ (some UVA protection) to PA++++ (extremely high). It complements SPF, which reflects only UVB protection.
