The quick version: A Korean skincare label lists every ingredient in descending order of content, shows a lot number and either an expiration date or a period after opening (with the manufacturing date), and is written in Korean. Products with regulated claims, such as sun protection or wrinkle improvement, are “functional cosmetics” and carry that designation (기능성화장품) plus reviewed efficacy wording. US-market versions follow FDA rules instead: English labels, and a Drug Facts panel for sunscreens.
A box covered in Hangul can feel like a wall. But a Korean skincare label follows a predictable structure set by Korean law, and once you know where to look, it tells you more than many American labels do. It also tells you, in one small phrase, whether a product’s key claim was reviewed by the government.
Here is how to read the essentials, what the Korean rules require, and how that compares with the labels you see in US stores.
What’s inside
What a Korean skincare label must show
Korean cosmetics are regulated by the Ministry of Food and Drug Safety (MFDS) under the Cosmetics Act and its Enforcement Rule. The official English translation of the Enforcement Rule, published by the Korea Legislation Research Institute, sets out what must appear on a package (Enforcement Rule of the Cosmetics Act). In practice, a full-size product shows:
- The product name and the company responsible for selling it
- All ingredients, in descending order of content
- The net contents
- A manufacturing (lot) number
- An expiration date, or a period after opening together with the manufacturing date
- Precautions for use
- For functional cosmetics, the reviewed or reported efficacy, directions and amount to use
Very small packages get a pass. Under the Enforcement Rule, products under 10 mL or 10 g, and trial samples, need only the product name, the seller’s trade name, the price, the manufacturing number and the expiration date or usage period. That’s why the tiny sachets tucked into K-beauty orders rarely carry a full ingredient list.
Labels must be easy to read in Korean, though Chinese characters or foreign languages may appear alongside. So a product made for the Korean market will always have its legally required information in Hangul, even if the front of the box is in English.
Worth remembering
- Korean labels list all ingredients in descending order of content.
- “기능성화장품” (functional cosmetic) means the product’s specific claim was evaluated by or reported to MFDS.
- A period after opening must come with a manufacturing date.
- US-market versions follow FDA rules: English labels, and a Drug Facts panel for sunscreens.
Reading the ingredient list on a Korean skincare label
Korea’s rule is that ingredients appear in descending order of content, using standardized ingredient names (Enforcement Rule of the Cosmetics Act). The US rule is similar: descending order of predominance, except that ingredients at 1% or less may follow in any order, and color additives may go at the end (FDA).
That gives you a few reliable reading habits:
- Look at the first five or so ingredients. They’re present in the largest amounts. In hydrating products you’ll often see water and humectants such as glycerin at the top.
- Find the hero ingredient. If a “cica” cream lists centella asiatica extract near the end, after the preservatives, there’s likely only a little of it. Our guide to centella asiatica explains what to look for; for snail products, look for “snail secretion filtrate,” as covered in our snail mucin guide.
- Spot fragrance. On US labels, fragrance may be listed simply as “fragrance” rather than by component (FDA). If your skin is reactive, fragrance-free is the simpler choice.
- Don’t treat percentages on the front as concentrations of an active. A big number usually describes how much of an extract or filtrate is in the formula, not how potent it is.
Many K-beauty fans read the English (INCI) ingredient list provided by the brand or retailer alongside the Korean one. If the product is sold through US retail, its label must be in English anyway.
“Functional cosmetic”: the most useful words on the box
Korea has a category with no direct US equivalent: functional cosmetics. MFDS defines them as cosmetics with functions defined in the Cosmetics Act. For skin, the categories include products aiding in improving wrinkles, protecting skin from UV rays or tanning it gently, alleviating acne breakouts, alleviating dryness from atopic-prone skin, and thinning red stretch-mark lines. A company that wants to sell one must have each product’s safety and effectiveness evaluated by MFDS or submit a report (MFDS).
One more category deserves a note on translation. MFDS’s English materials call it “whitening.” In practice these products are aimed at discoloration and uneven tone, and we prefer to describe them that way; “whitening” is a loaded word that doesn’t reflect what most readers want from skincare.
Functional cosmetics carry the Korean term 기능성화장품 on the label, along with approved efficacy wording and usage directions (ChemLinked). That’s why the phrase is worth finding: it means the specific claim, say wrinkle improvement, went through a government process rather than appearing only in marketing copy.
| Functional cosmetic category (skin) | Roughly comparable US status |
|---|---|
| UV protection | Over-the-counter drug (sunscreen) |
| Alleviating acne | May be regulated as a drug in the US, depending on the claim |
| Wrinkle improvement | Cosmetic, if it only claims to improve appearance |
| Discoloration (officially “whitening”) | Cosmetic, if it only claims to improve appearance |
| Dryness from atopic-prone skin | Cosmetic or drug, depending on the claim |
| Stretch-mark lines | Cosmetic, if it only claims to improve appearance |
The US comparison depends on intended use. The FDA treats a product as a drug if it is intended to treat or prevent disease or affect the structure or function of the body, and some products, such as moisturizers with sunscreen, are both cosmetics and drugs (FDA).
Expiration dates and periods after opening
Korean labels must show either an expiration date or a usage period after opening; if they use the latter, the manufacturing date must appear too (Enforcement Rule of the Cosmetics Act). That pairing is useful: you can tell how old an unopened product is, and how long it’s meant to last once opened.
The US works differently. The FDA states that no US law or regulation requires cosmetics to have specific shelf lives or expiration dates on their labels, although products that are drugs, including sunscreens and other drug-cosmetic combinations, must carry expiration dates. The agency also advises against storing cosmetics in heat, which can degrade preservatives (FDA).
A practical tip: write the opening date on the bottle with a marker. Products with a period after opening are counting from that day.
Sunscreen labels: SPF and PA
Korean sunscreens show SPF, usually up to “SPF 50+,” and a PA grade for UVA protection, from PA+ to PA++++, based on the persistent pigment darkening method (Patel and Patel, 2026). More plus signs mean more UVA protection.
US sunscreens are over-the-counter drugs and carry a Drug Facts panel instead, with active ingredients listed separately and the words “Broad Spectrum” if the product passes the FDA’s UVA test (FDA). A Korean sunscreen without a Drug Facts panel is a Korea-market product. Our guides to Korean sunscreen and mineral vs. chemical filters explain which Korean filters the FDA permits.
How US labels differ
| Label element | Korean market | US market |
|---|---|---|
| Language | Korean required | English required |
| Ingredient order | Descending order of content | Descending order; ingredients at 1% or less in any order |
| Expiration | Expiration date, or period after opening plus manufacturing date | Not required for cosmetics; required for drugs such as sunscreen |
| Regulated claims | “Functional cosmetic” with reviewed efficacy wording | Drug claims require a Drug Facts panel |
| Sunscreen | SPF and PA grade | SPF, “Broad Spectrum” and Drug Facts |
| Origin | Seller and manufacturer named | Name and place of business; country of origin for imports |
A few US marketing words have no regulatory meaning. The FDA states that there are no federal standards or definitions for “hypoallergenic,” and that the term means whatever a particular company wants it to mean (FDA). If you react easily, the full ingredient list and a patch test tell you more than any claim on the front.
Frequently asked questions
What does 기능성화장품 mean on a Korean label?
It means “functional cosmetic.” The product’s specific claim, such as UV protection or wrinkle improvement, was evaluated by or reported to Korea’s MFDS.
Why don’t my K-beauty samples list ingredients?
Korean rules let packages under 10 mL or 10 g, and trial samples, show only basic information such as the product name, seller, lot number and expiration.
How do I read the expiration date?
Look for either an expiration date or a period after opening paired with a manufacturing date. If the format is unclear, the manufacturing date plus the stated period tells you the timeline.
Is a Korean product without English labeling legal in the US?
Cosmetics sold in the US must carry their required label information in English, including the country of origin for imports. A Korean-only label is a sign the product was packaged for the Korean market.
Does “dermatologist tested” or “hypoallergenic” mean anything?
Not much in regulatory terms. The FDA says “hypoallergenic” has no federal definition. Read the ingredient list and patch test new products instead.
