Getting started

Patch test first — dab a little on your inner forearm or behind the ear and leave it a day before using it on your face. Introduce one new product at a time, a week or two apart, so you can tell what your skin is responding to. If anything stings, itches, or turns red, stop using it.

Where it goes in your routine

K-beauty layers thin to thick: cleanser → toner → essence, serum, or ampoule → moisturizer, and sunscreen last every morning. Let each layer settle for a moment before the next one — no need to wait for it to dry completely.

New to this? Our 4-product starter routine walks through the whole thing.

What not to layer at once

Exfoliating acids (AHA/BHA), vitamin C, and retinal are best kept apart — alternate them across mornings and evenings, or across days, rather than stacking them in one sitting. See the layering map for what pairs safely with what.

Storing your products

• Keep everything in a cool, dry spot out of direct sunlight — a shelf away from the shower steam beats the windowsill or the car.
• Close caps and droppers tightly. Vitamin C keeps its potency longest sealed and away from heat.
• Water-light textures like essences and ampoules are best finished within their open-jar period.
• No need to refrigerate — but a sheet mask chilled for ten minutes is a nice touch in summer.

Reading the date on Korean packaging

Korean cosmetics print dates as year-month-day (for example, 2027.03.15), with two common markings:

• 까지 (kkaji) or EXP — use by this date.
• 제조 (jejo) — the date it was made, not the expiry.

The open-jar symbol (12M, 6M…) tells you how many months the product stays fresh once opened. Unsure about a marking on your bottle? Send us a photo and we'll read it for you.

A note on ingredients

Some of K-beauty's most-loved ingredients — snail mucin, propolis, honey — are animal-derived, so check the ingredient list on the product page if a fully vegan formula matters to you. Curious what snail mucin actually does? We wrote about it honestly here.
