What 'Quasi-Drug' Means on a Japanese 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.

By count, the EU permits roughly 34 UV filters versus about 16 in the US. The gap exists largely because the US regulates sunscreens as over-the-counter drugs requiring extensive data, while the EU treats them as cosmetics. Bemotrizinol's June 2026 FDA approval was the first US addition in decades.

Not automatically — but Japanese and Korean sunscreens can use modern UVA filters within competitive cosmetics markets, so many feel lighter and cover more of the UVA range. Protection still depends on applying enough and reapplying; an elegant formula used sparingly underperforms a basic one used well.
