How to Read Korean Skincare Labels: Ingredients, Directions, and Warnings
By DK Editor, KpopDirect Beauty Desk · October 13, 2026 · Contact: contact@kpopdirect.com
If you buy Korean skincare in the US, you have probably held a box covered in Hangul and had no idea which part is the ingredient list and which part is a warning. The good news is that Korean cosmetic labels follow a fixed legal checklist. Once you know what that checklist is, you can find the useful information even if you can't read Korean.
This guide explains what Korean law requires on a skincare label, what the main sections mean in English, and what a label can and can't tell you. To keep things clear, we separate what the official rules say from our own reading of what that means for you.
Quick answer: On a Korean skincare label, look for four things: 전성분 (full ingredient list), 사용방법 (directions), 사용 시의 주의사항 (precautions), and the date section, which shows either 사용기한 (use-by date) or 개봉 후 사용기간 (period after opening) along with the manufacturing date. If the product is a 기능성화장품 (functional cosmetic), the label also lists the reviewed or reported effect and how to use it.
What's Inside
What a Korean Label Must Show
Under Korea's Cosmetics Act (Article 10), as summarized by the Korean government's EasyLaw cosmetics labeling page, the outer packaging has to show a set list of items. The ones that matter most when you are buying are below.
| Korean term | English | What it tells you |
|---|---|---|
| 화장품의 명칭 | Product name | What the product is officially called |
| 영업자의 상호 및 주소 | Business name and address | Who is responsible for the product |
| 전성분 | Full ingredients | Ingredients used to make it, with some legal exceptions |
| 내용량 | Net contents | Volume (ml) or weight (g) |
| 제조번호 | Batch number | Identifies the production batch |
| 사용기한 / 개봉 후 사용기간 | Use-by date / period after opening | How long the product is meant to stay usable |
| 사용할 때의 주의사항 | Precautions for use | Warnings and storage instructions |
| 기능성화장품 | Functional cosmetic | The product has a reviewed or reported effect, which must be stated with directions |
The same list also includes price, the content of any ingredient named in the product name, the content of human cell or tissue culture fluid if used, raw material content for products advertised as natural or organic, and country of manufacture for imported products.
Outer box vs bottle. Korean law separates the 1차 포장 (primary packaging, the container that touches the product) from the 2차 포장 (secondary packaging, the box or wrapping around it). When a product comes in a box, the bottle itself only has to show four things: the product name, the business name, the batch number, and the use-by date or period after opening (with the manufacturing date).
KpopDirect take: Before you throw away the box, take a photo of it. The bottle may not have the ingredient list or the precautions, and those are what you will want if your skin reacts later.
전성분: The Full Ingredient List
전성분 literally means "all ingredients." The rule is that the label lists every ingredient used to make the product, but there are exceptions. Ingredients that are removed during manufacturing and minor components already inside a raw material (such as a stabilizer or preservative, below the amount that has an effect) do not have to be listed.
Small sizes can skip part of the list. For products over 10 ml (or 10 g) and up to 50 ml (or 50 g), the brand may leave some ingredients off. It still has to list certain ones, including tar colors, AHA, the active ingredient of a functional cosmetic, and ingredients the Ministry of Food and Drug Safety has given usage limits. If a brand shortens the list, it has to give a phone number or website on the package, or keep a printed full list at the store, so you can check the full list right away. Products 10 ml or under and free samples can use an even simpler label, with the same rule about checking the full list.
Named ingredients come with a number. If an ingredient appears in the product name, for example a toner named after a plant extract, the label has to state that ingredient's content.
What about the order? In the US, the FDA requires cosmetic ingredients to be listed from highest to lowest amount, except that ingredients at 1% or less and color additives can go in any order (FDA labeling summary). The Korean government summary we checked doesn't spell out an ordering rule, so we don't assume the Korean list follows the same one.
KpopDirect take: A percentage in a product name tells you how much of that one ingredient is in it, not whether the formula suits you. A higher number is not automatically better, especially with acids. Use the full list mainly to spot ingredients you already know irritate your skin.
사용방법 and Functional Cosmetics
사용방법 means "directions" or "how to use." For most skincare, this is the brand's own instruction, such as when in the routine to apply it and how much.
Functional cosmetics (기능성화장품) are different. Their label must say "기능성화장품" or show the official symbol, and it must state the effect that was reviewed or reported to the regulator, along with the usage and amount (용법·용량). So on a functional product, the directions are part of what the product was reviewed for, not just a suggestion from the brand.
Four types of functional cosmetics also have to carry the phrase "질병의 예방 및 치료를 위한 의약품이 아님", which means "not a medicine for preventing or treating disease." These are products that help ease hair loss symptoms, cleansing products that help soothe acne-prone skin, products that help restore the skin barrier to relieve things like itching, and products that help fade red stretch marks.
KpopDirect take: Take that phrase at face value. An acne-prone-skin cleanser or a barrier cream can be a useful part of daily care, but it is not a treatment for acne, eczema, or rosacea. If a skin condition keeps coming back or getting worse, see a board-certified dermatologist.
Use-By Date vs Period After Opening
A Korean label shows one of two dates, and they are easy to mix up.
| Label term | Official meaning | How to use it |
|---|---|---|
| 사용기한 (use-by date) | The minimum period from manufacture during which the product, stored properly, keeps its properties and can be used stably | A fixed date printed on the package |
| 개봉 후 사용기간 (period after opening) | How long to use the product after opening; must be shown with the manufacturing date (제조연월일), and may use a symbol plus the period | Count from the day you open it |
| 제조번호 (batch number) | Required on both the box and the bottle | Keep it if you need to report a problem |
KpopDirect take: If your label shows a period after opening, write the opening date on the bottle with a marker. You can see the manufacturing date, but you can't see when you opened it, and that is the date the period after opening counts from.
사용 시의 주의사항: Precautions
Most of the warning text on Korean skincare comes from Annex 3 of the Enforcement Rule of the Cosmetics Act, which sets common precautions for all cosmetics and extra ones for certain product types. That's why so many Korean products have nearly the same warning paragraph.
Common precautions (all cosmetics): consult a specialist if red spots, swelling, itching, or other reactions appear on the area of use, including from direct sunlight, during or after use. Avoid using on areas with wounds. Keep out of reach of children. Store away from direct sunlight.
Extra precautions you may see on skincare:
- Scrub cleansers with fine grains: if grains get in the eyes, rinse with water and consult a specialist if there is a problem.
- Packs (팩): use away from the eye area.
- Non-aerosol spray sunscreen: do not spray directly on the face; spray into your hand and apply.
- Products with more than 0.5% AHA: use with sunscreen because AHA can increase sun sensitivity (not required for wash-off or hair products), and test on a small area first. Products with more than 10% AHA or a pH below 3.5 must also say to consult a specialist because of the higher risk of side effects.
If you are comparing acid products, our AHA vs BHA vs PHA guide explains how these acids differ.
KpopDirect take: Because the common warning is the same on almost every product, it tells you little about one product compared with another. The product-specific lines, like the AHA warnings, are the ones worth reading closely. If you react easily, our Korean skincare for sensitive skin guide covers how to introduce new products slowly.
Real Example: Korean Wording in English
We could not reliably read full label images on brand websites, so rather than guess at one product's label, we used wording that the law requires and that appears across many Korean products. The left column is the official text. The right column is our interpretation.
| Korean on the label (official) | Literal English | What it means for you (our reading) |
|---|---|---|
| 상처가 있는 부위 등에는 사용을 자제할 것 | Refrain from using on areas with wounds, etc. | Skip broken, scratched, or freshly picked spots. |
| 어린이의 손이 닿지 않는 곳에 보관할 것 | Keep out of reach of children | Standard storage rule, not a sign the product is unusually risky. |
| 직사광선을 피해서 보관할 것 | Store away from direct sunlight | Don't leave it on a sunny windowsill or in a hot car. |
| 일부에 시험 사용하여 피부 이상을 확인할 것 | Test on a small area to check for skin problems | Seen on AHA products. Try a small area for a few days before using it on your whole face. |
| 자외선 차단제를 함께 사용할 것 | Use together with sunscreen | If you use this product, wear daily sunscreen too. It doesn't mean the two products must be layered at the same moment. |
| 질병의 예방 및 치료를 위한 의약품이 아님 | Not a medicine for preventing or treating disease | Can support skin care, but it is not a treatment. |
KpopDirect take: A phone translation app is fine for this boilerplate text. Where translation apps often go wrong is the date section and the ingredient names, so check those against the terms in this guide.
Korean Label vs US Label
A Korean product sold in the US may not carry the same label you would see in Seoul. Korean law allows products made only for export, and not sold in Korea, to follow the importing country's rules instead of Korea's labeling rules. For the US, the FDA requires required label statements to be in English, and imported products must state the country of origin in English.
Sunscreen is the biggest difference. In the US, products meant to protect against sunburn are regulated as drugs as well as cosmetics. These over-the-counter products use the standard Drug Facts label, which lists active ingredients first, then purpose, uses, warnings, directions, inactive ingredients, and other information.
| Point | Korean domestic label | US label |
|---|---|---|
| Language | Korean | Required statements in English |
| Ingredient order | Not stated in the summary we checked | Highest to lowest amount; 1% or less and colors in any order |
| Sunscreen | Follows Korean cosmetics rules | OTC drug with a Drug Facts panel |
| Export-only products | May follow the importing country's rules | US rules apply |
KpopDirect take: If you find two versions of the "same" product, one with a Korean label and one with an English label, don't assume the formulas or claims are identical. Compare the ingredient lists side by side.
Checklist Before You Buy
- Find 전성분. Check for ingredients that have irritated your skin before. If it's a mini size with a shortened list, use the phone number or website on the package to see the full list.
- Check for 기능성화장품. If it's there, read the stated effect and the directions that come with it.
- Look for AHA warnings. A line saying to use sunscreen or consult a specialist tells you the product contains AHA, and at the higher level, more than 10% or a pH below 3.5.
- Read the date section. Is it a use-by date or a period after opening? If it's a period after opening, note the manufacturing date too.
- Know which label you have. A Korean domestic label and a US label can differ, especially on sunscreen.
- Keep the box or a photo of it. The full information is often only on the outer packaging.
A label can tell you what's in a product and how it's meant to be used. It can't tell you how your skin will respond. If a product causes burning, swelling, or a rash that doesn't settle after you stop using it, see a dermatologist.
FAQ
Why does my mini-size Korean product have a shorter ingredient list?
Korean rules allow products from over 10 ml up to 50 ml to leave off some ingredients, as long as certain ones are still listed and you can see the full list through a phone number, website, or printed list at the store. Products 10 ml or under and samples can use a simpler label.
Is 사용기한 the same as an expiration date?
Close, but the official meaning is the minimum period from manufacture during which the product, stored properly, stays stable. A period after opening (개봉 후 사용기간) is different. It counts from the day you open the product.
Does "기능성화장품" mean the product is a medicine?
No. It is still a cosmetic, but one with a reviewed or reported effect. Some functional types must say outright that they are not medicines for preventing or treating disease.
