K-Beauty Fragrance Allergens: Reading EU and US Cosmetic Labels
A Q&A on fragrance allergen labels, EU transition dates and questions to ask before buying Korean cosmetics.
When a Korean skincare product is sold in more than one market, fragrance information on its packaging can look different. The differences are useful to understand if you shop internationally or need to avoid a particular ingredient. This guide describes EU and US labeling information, not a guarantee about any individual product.
Why might an EU ingredient list name individual fragrance substances?
The European Commission explains that fragrance mixtures may generally appear as parfum or aroma, while certain listed fragrance allergens must also be named individually above defined concentrations. The 2023 EU amendment added individual labeling requirements for 56 fragrance allergens. The thresholds are above 0.001% for leave-on products and above 0.01% for rinse-off products.
Do the new EU labels all appear at once?
No. The Commission says products that do not meet the new requirements could no longer be placed on the EU market from 31 July 2026. Products placed on the market before that date may continue to be made available until 31 July 2028 under the transition rules. An older-looking label alone does not establish when a specific item was placed on the market.
How can a US label differ?
The US FDA explains that certain fragrance ingredients may be collectively declared as fragrance or perfume without naming each component. Consequently, an ingredient list may not answer every question about a fragrance mixture. Do not assume that a market-specific label is a complete breakdown of that mixture.
Does a named allergen mean the product is unsafe for everyone?
No. The European Commission says listing an ingredient does not itself mean the product is unsafe. Individual disclosure can help people who are already sensitized to a particular substance identify it. Conversely, not seeing a name does not establish absence in every circumstance, including when a disclosure threshold applies.
What should an international K-Beauty shopper ask?
- Confirm the exact product, version, destination market and current full ingredient panel, including the outer package when available.
- If you need to avoid a known substance, ask the manufacturer whether that specific ingredient is present in the exact formula; a short marketing claim may not answer the question.
- Do not assume a seller photo represents the batch shipped or that two markets necessarily use the same formula. Ask for current information when it matters to your purchase.
- If a reaction occurs, stop using the product and consult a qualified clinician as appropriate.
