Why You Can't Legally Buy That Viral Japanese Sunscreen in the US
Importing that viral Japanese sunscreen is a gray area, and the reason is regulatory.
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.
Frequently asked questions
How many UV filters are approved in the US vs the EU?
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.
Are Korean and Japanese sunscreens better?
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.
Is it safe to buy sunscreen overseas?
Buying reputable sunscreen abroad is generally fine, but check the expiration date, store it away from heat, and note that US import rules treat sunscreen as a drug. Counterfeit or heat-damaged products can lose effectiveness, so purchase from trusted retailers.
