Every few months, a post goes viral claiming that Europe bans more than a thousand cosmetic ingredients while the US bans barely a dozen. The numbers are usually right, but they compare only two markets. We wanted the full picture, so we counted the ingredient restrictions in all 10 markets our database covers.
The gap is wider than the usual comparison suggests. The EU accounts for 5,301 ingredient restrictions in our data. The US has 111. The eight markets in between fall into a pattern that says more about regulatory philosophy than about safety.
The ranking
Each number below counts how many cosmetic ingredient restrictions — prohibitions plus concentration limits — each market has in our regulatory database.
| Rank | Market | Total | Prohibited | Restricted |
|---|---|---|---|---|
| 1 | EU | 5,301 | 4,039 | 1,262 |
| 2 | ASEAN | 4,843 | 3,891 | 952 |
| 3 | China | 4,145 | 3,373 | 772 |
| 4 | Korea | 4,046 | 3,356 | 690 |
| 5 | Brazil | 4,022 | 3,220 | 802 |
| 5 | Argentina | 4,022 | 3,220 | 802 |
| 7 | Taiwan | 2,137 | 1,459 | 678 |
| 8 | Canada | 1,947 | 1,699 | 248 |
| 9 | Japan | 386 | 95 | 291 |
| 10 | US | 111 | 30 | 81 |
The top four — the EU, ASEAN, China, and Korea — cluster between roughly 4,000 and 5,300 restrictions. Then the numbers fall off a cliff. Canada has fewer than half of Korea's. Japan has fewer than a tenth. The US has about one-fiftieth of the EU's total.
The two extremes
The EU and the US sit at opposite ends because they regulate cosmetics in opposite ways.
The EU works from a prohibition list. Its cosmetics regulation maintains a banned-substances annex with thousands of entries, and an ingredient is presumed disallowed once a committee flags a concern. This is the precautionary principle: restrict first, allow once safety is shown. The list grows almost every year.
The US works from the opposite default. With the exception of color additives, a manufacturer can use almost any raw material without pre-market approval. The FDA's outright-ban list is famously short — around 11 substances, including mercury compounds, chloroform, and vinyl chloride. Our database shows 111 US entries because it also captures color-additive restrictions, which are the one category the FDA reviews before market. Even counted generously, the US regulates a fraction of what the EU does, and it relies on post-market enforcement rather than a long prohibition list.
Neither number measures whether products are actually safer in one market than the other. A long list reflects a method, not an outcome.
Japan, the outlier
Japan is the only market in the set where restrictions outnumber prohibitions: 291 concentration limits against 95 outright bans. Every other country bans far more than it limits.
That inversion reflects Japan's positive-list approach to certain ingredient categories. Preservatives, UV filters, and colorants are governed by lists of what is allowed at what concentration, rather than long catalogs of what is forbidden. The result is a system that looks small by a banned-substance count but controls ingredients through a different mechanism.
Brazil and Argentina, identical to the digit
Brazil and Argentina have the same numbers in every column: 4,022 restrictions, 3,220 prohibited, 802 restricted. Not approximately the same — identical.
That is not a coincidence in the data. Both are members of MERCOSUR, the South American trade bloc, which harmonizes cosmetic ingredient rules across member states. When the bloc updates its common list, both countries move together. The matching numbers are a fingerprint of shared regulation.
Where Korea sits
Korea ranks fourth, with 4,046 restrictions — close behind China, and within the top cluster. For a market often described as having strict, detailed cosmetic rules, that placement fits. It regulates more ingredients than Canada, Japan, and the US combined, several times over.
But it trails the EU by more than 1,200 restrictions. The pattern we have seen across individual ingredients — retinoids, parabens, vitamin C — holds at the aggregate level too: the EU is consistently among the first to restrict, and Korea often follows rather than leads.
What a high count does not mean
The ranking is easy to misread as a safety scoreboard, with the EU at the top and the US at the bottom. It is not.
A restriction count measures how a market writes its rules, not how safe its products are. The EU's long list comes from a precautionary, list-based system. The short US list comes from a post-market system that leans on enforcement, recalls, and liability rather than pre-emptive bans. A country can regulate few ingredients and still act aggressively after a problem appears, or regulate many and enforce unevenly. None of that shows up in a count of restrictions.
What the count does show is regulatory burden. For a company selling across markets, the practical signal is direction: a formula cleared for the US market may face thousands more restrictions in the EU, while a formula built to EU standards will usually clear everywhere else in the set.
What the data does not show
Our database tracks the restrictions recorded for each market, not the enforcement behind them. A market with a long list and weak enforcement and a market with a short list and strong enforcement can produce similar real-world outcomes that these numbers do not capture.
The counts also reflect what each market publishes in a form we can collect. Markets that regulate through positive lists, like Japan, or through references to other frameworks may carry restrictions that a banned-substance count understates. The figures are a consistent comparison of prohibition-style restrictions, not a complete map of every regulatory tool.
Regulations change constantly. The EU adds substances most years, and several markets in this set have updates pending. The ranking is a snapshot.
Methodology and Sources
Ingredient and regulatory data: K-Beauty Cosmetic Ingredients database, covering 21,796 ingredients across 10 markets — the EU, ASEAN, China, Korea, Brazil, Argentina, Taiwan, Canada, Japan, and the US.
Counts are of regulatory entries classifying an ingredient as prohibited or restricted in each market. A small number of ingredients carry more than one entry per market; counting distinct ingredients instead changes the totals by about one percent and does not change the ranking. US figures include FDA color-additive restrictions alongside prohibited substances; the FDA's core outright-ban list is shorter, around 11 substances.
Regulatory-philosophy context — precautionary versus post-market regulation, MERCOSUR harmonization, and Japan's positive lists — was cross-checked against regulatory and trade-press sources.
