How to read a K-beauty ingredient list
An ingredient list looks like a wall of Latin. A few simple habits make it much easier to read.
Last updated November 3, 2026. General information, not medical advice.
Where to find it
On the outer box, the label of the tube or bottle, or the retailer's product page. Use the list on the box you actually receive. The same product can be made in slightly different versions for different countries, so a list copied from another site may not match yours.
Order matters, up to a point
In the US, ingredients are listed from the largest amount to the smallest. The exception is anything at or below 1% of the formula, which can appear in any order. So the first few ingredients (usually water and a few base ingredients) make up most of the product, and the long tail is hard to compare.
A big number on the front, such as "77% extract," usually refers to one ingredient or extract. The list shows everything else in the formula.
Names you will see often
Ingredient lists use standard scientific names, not the friendly names on the front. These are common in Korean skincare:
- Centella Asiatica Extract: often sold as "cica" or "tiger grass," and used in soothing products.
- Houttuynia Cordata Extract: heartleaf.
- Artemisia Princeps Leaf Extract: Korean mugwort.
- Snail Secretion Filtrate: snail mucin.
- Sodium Hyaluronate: a form of hyaluronic acid, a common moisturizing ingredient.
- Niacinamide: vitamin B3, used in many serums and creams.
- Panthenol and Allantoin: common soothing, conditioning ingredients.
- Ceramides (for example Ceramide NP): skin-barrier ingredients in many moisturizers.
- Propolis Extract, Oryza Sativa (Rice) Extract and Camellia Sinensis (Green Tea) Leaf Extract: plant-based ingredients that appear across the category.
- PDRN or Sodium DNA: a newer ingredient that has become popular in serums.
What an ingredient does depends on how much is in the formula, which the label doesn't tell you. Brand claims describe what the ingredient is used for, not a promise about your skin.
Ingredients worth a second look
- Fragrance (Parfum) and essential oils. These are common causes of irritation for people with sensitive skin. Many Korean products are labeled fragrance-free. Check the list, not just the front.
- Alcohol Denat. or SD Alcohol. Can feel drying to some people. Fatty alcohols such as Cetyl Alcohol and Cetearyl Alcohol are a different thing and are common in creams.
- Exfoliating acids (glycolic and lactic acid, which are AHAs; salicylic acid, a BHA; gluconolactone, a PHA). Start slowly, and use sunscreen in the daytime because they can make skin more sensitive to the sun.
- Retinol and other retinoids. Same advice: build up gradually and wear sunscreen.
- Vitamin C (Ascorbic Acid and its derivatives). Can sting some skin, and some forms spoil when exposed to air and light.
Before you buy
- Compare the list on the box with the one on the product page.
- If you have a known allergy, check the full list for it, and look for brand notes on allergens.
- Patch test a new product, for example on the inner arm or behind the ear for a day or two, before using it on your face.
- Stop using a product if it causes burning, swelling or a rash, and see a doctor if it doesn't clear up.
