Why most Korean sunscreens aren't sold in the US (October 2026 update)

Short answer: the US treats sunscreen as a drug and allows only 15 UV filters. South Korea treats it as a functional cosmetic and allows 29 — including the newer filters that give many K-beauty sunscreens their light, non-white finish.

Two different rulebooks

• United States: sunscreens are over-the-counter (OTC) drugs. A product can only use active ingredients listed in FDA's sunscreen monograph (M020), at or below set limits. Adding a new filter requires a formal FDA order backed by safety and efficacy data.
• South Korea: sunscreens are functional cosmetics. Every product must be reported to or reviewed by the Ministry of Food and Drug Safety (MFDS) before sale, with its SPF and PA rating, and may use filters from Korea's approved list.

Because a Korean formula that uses even one filter missing from the US list cannot be sold as a US sunscreen, brands either skip the US market or make a separate US formula.

Filters allowed in Korea but not in the US (14)

What changed in 2026

• Bemotrizinol (Tinosorb S) is now allowed in the US, up to 6% — FDA final order published June 10, 2026, effective August 9, 2026. It has long been allowed in Korea (up to 10%) and the EU. Details
• PABA and trolamine salicylate are being removed from the US list (FDA order, September 2026, effective September 2027). FDA says it knows of no current US sunscreens that use them.
• Other filters common in Korean sunscreens — bisoctrizole (Tinosorb M), Uvinul A Plus, ethylhexyl triazone, iscotrizinol, polysilicone-15 — are still not on the US list.

Does this mean Korean sunscreens are better — or unsafe?

Neither, by itself. Each filter on Korea's list is approved by Korean regulators, and most are also approved in the EU. The short US list mostly reflects how hard it is to add an ingredient to the US drug monograph. Judge a product by its registered SPF/PA, its ingredients, and how it suits your skin.

How to read the label

US sunscreens show a Drug Facts box listing active ingredients. Korean sunscreens list all ingredients in Korean on the box; Korean names for each filter are on the filter pages. To check that a product is genuine, see how to check a Korean sunscreen is genuine.

FAQ

Why can't I find my favorite Korean sunscreen in US stores?

In the US, sunscreen is regulated as an over-the-counter drug and may only use active ingredients on FDA's sunscreen monograph — 15 filters today. Korea allows 29, including modern filters such as bisoctrizole (Tinosorb M) and Uvinul A Plus that are not on the US list.

Is Tinosorb S (bemotrizinol) allowed in the US now?

Yes. FDA added bemotrizinol at up to 6% to the OTC sunscreen monograph by a final order published June 10, 2026, effective August 9, 2026. It was the first new US sunscreen filter since the late 1990s.

Is it illegal to buy a Korean sunscreen online in the US?

This site does not give legal advice. Retail sale in the US requires compliance with FDA's sunscreen rules; personal imports are a separate question handled by FDA and US Customs. Check FDA's guidance for your situation.

How do I know a Korean sunscreen is genuine?

Korean sunscreens must be registered with the Ministry of Food and Drug Safety. Compare the Korean product name and SPF/PA on your box with the registry entry — you can search it on this site.
