Sunscreen UV Filters: A 10-Country Comparison

A sunscreen formulated for sale in Seoul cannot always be sold as-is in New York, Paris, or São Paulo. Each country maintains its own list of permitted UV filters, and the lists rarely match. A filter that is legal at 10% in one market may be banned in the next, or capped at 5%, or allowed only in specific product types. We mapped UV filter approvals across 10 markets — the EU, Korea, Japan, China, Taiwan, ASEAN, the US, Canada, Brazil, and Argentina — using a structured database of 21,796 cosmetic ingredients with 30,960 regulatory records. Below is what the data shows. What every country agrees on Two UV filters are approved in all 10 markets: Zinc Oxide — mineral filter, broad spectrum (UVA + UVB) Titanium Dioxide — mineral filter, UVB and partial UVA These are the only filters with universal approval. Any formulation designed to sell identically across all 10 markets without reformulation must rely on these two ingredients. This is why most global brands lead with minera...

Banned in Europe, Legal in Korea: 5 Ingredients That Split Global Regulators

The same moisturizer that sits on a shelf in Seoul could be pulled from a store in Paris. Not because of a labeling error or a packaging defect — but because an ingredient inside is classified differently by two governments looking at the same scientific data. This happens more often than most consumers realize. The EU and South Korea — both major cosmetics markets with sophisticated regulatory systems — frequently disagree on where to draw the line. The EU's cosmetics regulation (EC 1223/2009) maintains one of the strictest banned substance lists in the world, with over 1,600 entries in Annex II. Korea's MFDS takes a different approach, often allowing the same ingredients under specific concentration limits or without restriction. Neither system is wrong. They operate under different regulatory philosophies: the EU leans toward the precautionary principle — restrict first, revisit later. Korea tends toward risk management — allow under controlled conditions, monitor outcomes...

Your 20% Vitamin C Serum Has No Concentration Limit. In Any Country.

Vitamin C serums are sold at 10%, 15%, 20%, and sometimes 30% concentration. These are high numbers for an active ingredient. For comparison, the EU recently capped retinol at 0.3% in most cosmetics. So how is 20% vitamin C legal when 0.3% retinol is the EU limit? Because no country regulates L-Ascorbic Acid concentration in cosmetics. None of the 10 markets in our database — EU, Korea, Japan, China, Taiwan, ASEAN, Brazil, Argentina, the US, or Canada — has a limit. 76 forms of vitamin C Our database contains 76 ingredients with "Ascorbic" or "Ascorbyl" in their INCI names. Vitamin C in skincare is not a single ingredient — it is a family of compounds, each with different stability, potency, and skin penetration characteristics. The ones consumers encounter most often: Form INCI name Characteristics L-Ascorbic Acid Ascorbic Acid Most potent, least stable. Requires low pH. The form used in 10–20% serums MAP Magnesium Ascorbyl Phosphate Stable,...
