Bioderma, La Roche-Posay, Beauty of Joseon: A Global Sunscreen Tour
The international cult favorites, and what actually makes them special.
Japan's PA system rates UVA from PA+ (PPD 2-4) up to PA++++ (PPD 16+).
In South Korea, sunscreens are 'functional cosmetics' that must pass MFDS evaluation before sale.
Questions we get a lot
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.
