U.S. Market Entry

K-Beauty Compliance Guide: Launch Korean Cosmetics in the U.S.

What Korean cosmetic brands need to know about FDA MoCRA, ingredient restrictions, and drug-cosmetic boundaries before selling in the United States.

The U.S. Regulatory Landscape for K-Beauty

The U.S. cosmetics market is governed by the FDA under the Modernization of Cosmetics Regulation Act (MoCRA). Unlike Korea's MFDS quasi-drug system, the U.S. draws a hard line between cosmetics and drugs. Ingredients classified as "functional" in Korea — whitening, anti-wrinkle, UV protection — often trigger drug status in the U.S. if they make structure/function claims.

Key differences:

  • No quasi-drug category in the U.S. — a product is either a cosmetic or an OTC drug
  • MoCRA facility registration required for manufacturers and packagers
  • Serious adverse event reporting mandated within 15 business days
  • Fragrance allergens are not required on U.S. labels (unlike EU)

Common K-Beauty Ingredients That Hit U.S. Boundaries

Many hero ingredients in Korean skincare fall into U.S. drug territory when paired with certain claims. Here are the most frequent boundary crossings we see:

Niacinamide (2-5%)

Safe as a cosmetic ingredient. But if claimed to "treat acne" or "reduce hyperpigmentation," the product may be regulated as a drug.

Retinol / Retinoids

Concentration matters. Low-dose retinol in anti-aging cosmetics is generally acceptable. Higher concentrations or acne claims push into OTC drug territory (21 CFR 358).

AHAs (Glycolic, Lactic Acid)

FDA has issued guidance on AHA concentrations in cosmetics. Products with high AHA levels and exfoliation claims may face scrutiny.

Sunscreen Filters

Only FDA-approved UV filters can be used in U.S. sunscreens. Many newer Korean filters (e.g., Tinosorb S, Uvinul A Plus) are not yet approved. Check our sources page for the current FDA sunscreen monograph.
