How To Read Korean Skincare Labels: Expiry Dates, Ingredients & Key Terms Explained (2026)
By Victoria | K-Beauty Basics · Education
You've found a Korean skincare product you want to try — but the packaging is entirely in Korean. The ingredient list, the instructions, the cautions, the expiry date. How do you know when it expires, how to use it, or what's actually in it?
Reading Korean skincare labels is much more manageable than it looks — once you know what to look for and where to find it. This guide covers everything: expiry dates, ingredient lists, usage instructions, common warnings, and the Korean skincare certifications worth knowing. No Korean language knowledge required.
Victoria's Note: At K&Global, reading and interpreting Korean cosmetics labels was a daily task — not just for understanding products myself, but for translating key information for international buyers who needed to verify ingredients, certifications, and expiry dates before importing. The information in this guide is exactly what I used to brief buyers on before their first Korean product orders.
Finding the Expiry Date
This is the first thing most international buyers want to know — and thankfully, expiry date formats are consistent across Korean products.
Korean expiry date formats:
- 까지 (kkaji) = "until" — followed by the expiry date
- 사용기한 (sayong gihan) = "use by date"
- 제조일자 (jejo iljja) = "manufacturing date"
- Date format: YYYY.MM.DD or YYYY/MM or YY.MM
- Example: 2027.06 = expires June 2027
Many Korean products also use the international Period After Opening (PAO) symbol — an open jar icon with a number and "M" (e.g., 12M = use within 12 months of opening). This is the same symbol used on European products.
Reading the Ingredient List (전성분)
The ingredient list on Korean skincare products is labeled 전성분 (jeonseongbun) — literally "all ingredients." Korean cosmetics follow the same INCI (International Nomenclature of Cosmetic Ingredients) system used globally, meaning ingredient names are listed in Latin/English on most Korean products sold internationally, even when the rest of the label is in Korean.
Key rules for reading any ingredient list:
Descending concentration order. Ingredients are listed from highest to lowest concentration. The first ingredient is present in the largest amount; ingredients near the end are present in trace quantities. An ingredient appearing in the first 5 is present at a meaningful concentration; one at position 25 of 30 may be present in less than 1%.
The 1% threshold. Ingredients present below 1% can legally be listed in any order after the 1% line. This is why you'll sometimes see fragrance or preservatives appearing before ingredients they should logically follow by concentration. Active ingredients at sub-1% concentrations may still be effective — but position tells you relative concentration for everything above 1%.
Water = Aqua = 정제수. Most skincare products begin with water, listed as Water, Aqua, or in Korean as 정제수 (jeongjesu — purified water). If water is the first ingredient, it's the base of the formula.

기능성화장품: Korea's Functional Cosmetic Classification
This term is unique to Korea and doesn't have a direct equivalent in Western cosmetics regulation. 기능성화장품 (functional cosmetic) is a Korean MFDS (Ministry of Food and Drug Safety) classification for cosmetics that contain regulated active ingredients with proven clinical efficacy in specific categories.
The MFDS-regulated functional cosmetic categories are:
- 미백 (mibaek) — Whitening/brightening (contains MFDS-approved brightening actives like niacinamide, alpha-arbutin, vitamin C)
- 주름개선 (jureum gaeseon) — Wrinkle improvement (contains adenosine, retinol, or other MFDS-approved anti-aging actives)
- 자외선차단 (ja-oe-seon chadahn) — UV protection (SPF products)
- 탈모 완화 (talmo wanwa) — Hair loss improvement
- 여드름성 피부 완화 (yeodeumsseong pibu wanwa) — Acne-prone skin improvement
When you see 기능성화장품 on a Korean skincare label, it means the product has been reviewed and approved by the MFDS for that specific claim — it's a regulatory certification, not marketing. This is why Korean anti-wrinkle claims are more trustworthy than comparable Western claims, which don't require the same level of regulatory approval.
Common Usage Instructions (사용방법)
Even when the usage instructions are in Korean, a few key phrases appear consistently:
- 세안 후 (se-an hu) = "After cleansing"
- 적당량 (jeokdangnyang) = "An appropriate amount"
- 피부에 바르다 (pibu-e bareuda) = "Apply to skin"
- 가볍게 두드리다 (gabyeopge dudeurida) = "Pat gently"
- 흡수시키다 (heupsuisikida) = "Allow to absorb"
- 아침/저녁 (achim/jeonyeok) = "Morning/Evening"
- 눈 주위를 피하다 (nun juwie piha) = "Avoid eye area"
Useful Apps for Reading Korean Labels
Hwahae (화해) — Korea's largest beauty app. Scan or search any Korean product to see full ingredient lists, safety ratings, user reviews, and MFDS certification status. Available in Korean; some interface in English for popular global products.
INCI Decoder / INCIBeauty — Enter any ingredient name (Korean or INCI) to get a plain-language explanation of what it does and its safety rating.
Google Lens / Naver Papago — Point your camera at Korean text for instant translation. Papago is particularly accurate for Korean cosmetics terminology.
Olive Young Global — The international version of Olive Young lists ingredient information and usage instructions in English for most products, even when the physical packaging is in Korean.
Final Thoughts
Reading Korean skincare labels becomes intuitive quickly — a handful of terms covers 90% of what you need to understand. Once you know where to find the expiry date, how to read the ingredient list, and what 기능성화장품 means, you can shop Korean skincare with confidence regardless of the language on the packaging.
Bookmark this guide for your next Olive Young haul or Amazon K-beauty order — and remember that most Korean products sold internationally include English ingredient lists alongside the Korean text, making verification straightforward even without translation tools.
