Korean sunscreen and the FDA: what the filter list actually allows

Start with the rule, because everything else follows from it. In the United States, sunscreen is not a cosmetic. The FDA regulates it as an over-the-counter drug, which means a sunscreen sold here has to be built from a defined list of permitted active ingredients — the UV filters. A brand cannot simply use a filter that works well elsewhere. It has to be on the list.

That list barely moved for a generation. From the late 1990s until 2026, no new UV filter was added to it, while Korea, Japan and the EU approved and refined a whole generation of newer ones. That is the gap this page is about, and it is the reason a Korean sunscreen can feel so much better than an American one at the same SPF.

The SPF on the bottle is a claim, and every country decides for itself whose claims it will check. The US checks the filter list first.

What changed in 2026 — and what didn't

In June 2026 the FDA approved bemotrizinol, the filter BASF sells as Tinosorb S, with the final order taking effect on 9 August 2026. It is the first new active added to the US sunscreen monograph since the late 1990s, it is broad-spectrum across UVA and UVB, and it is photostable — it keeps working in sunlight rather than degrading.

It is a genuine change, and it is also narrower than the coverage suggested. Korean sunscreens rarely rely on one filter; they blend several. Uvinul A Plus, Uvinul T150, Tinosorb M and Uvasorb HEB remain unapproved in the United States. A formula built on those filters cannot be sold here as a sunscreen no matter how well it performs, and reformulating around a shorter list is not a relabelling job — it is a different product. So the approval opens a door rather than a floodgate.

Why Korean sunscreen is regulated differently at home

Korea treats sunscreen as a functional cosmetic. A product is reviewed by the Ministry of Food and Drug Safety, and a brand may only print an SPF or PA figure once it has passed defined testing. So the number is tested — that part is real, and it is worth saying plainly, because "not FDA approved" is often misread as "made up". It was tested to Korean methods under Korean rules, and the FDA has never assessed it.

So can you buy and use them?

People do, in large numbers. What you are buying is generally an import rather than a US-regulated sunscreen: it may reach you through a retailer that brings it in, and it has not been through the FDA's OTC drug process. Read the SPF as the manufacturer's tested claim rather than an independently assessed US figure, and know that a product sold here as a cosmetic is not permitted to make US sunscreen claims in the first place.

Two practical consequences. Check where a seller is shipping from, because storage and handling in a grey-market chain are worth more thought than with a drugstore purchase. And check the date — sunscreen degrades, and imported stock can sit longer.

How we'd think about it

The evidence for daily sunscreen is not in question; the American Academy of Dermatology and the Skin Cancer Foundation both put it near the centre of sun protection. The most reliable baseline is a broad-spectrum, FDA-regulated sunscreen applied generously and reapplied, because that is the product whose claim has been assessed under US rules.

A Korean sunscreen can still be the one you actually wear, and that matters more than most people allow — the best sunscreen is the one you will put on every morning without resenting it. Go in understanding which of the two things you are buying. When we review a Korean SPF we say whether its filters are US-approved, and we make no therapeutic claims: we point you to the authorities above.
