100% Authentic Guaranteed

Directly sourced from Seoul, Korea — genuine products only.

Korean skincare is sold by volume or weight rather than by garment-style sizes. Here's how to read what's on the bottle — and how to choose when a product comes in more than one size.

How Sizes Are Written

ml (milliliters) — liquid volume. Used for toners, essences, ampoules, serums, cleansers, and sunscreen.
g (grams) — weight. Used for thicker textures in jars and sticks: creams, balms, and most makeup. A 50 g cream and a 50 ml cream are close in size but not identical, since weight depends on the formula.
ea (each) — number of pieces. Sheet masks are sold as single sheets (1 ea) or in boxes (10 ea).

Typical Sizes by Product Type

The sizes you'll see most often across our catalog, with a rough guide to how long one bottle lasts. These assume once- or twice-daily use on the face — your own pace will vary.

Product	Common sizes	Roughly lasts
Toner	150–500 ml	2–4 months
Essence, ampoule, serum	30–100 ml	2–4 months
Cream, moisturizer	50–70 ml / g	2–3 months
Cleanser	100–200 ml	2–3 months
Sunscreen	40–50 ml	4–6 weeks
Sheet mask	1 ea or 10 ea box	—

Choosing Between Two Sizes

Trying it for the first time? Start with the smaller size — it's the cheaper way to find out whether a formula suits you.
Already a repeat buy? The larger size is usually better value per milliliter.
Check the open-jar period. The small jar symbol on the packaging (12M, 6M…) tells you how many months the product stays fresh once opened. If you won't finish a 500 ml toner within that window, two smaller bottles keep better. Our FAQs explain how to read Korean date markings.
Sunscreen is the one to size up. A proper face application is about a quarter teaspoon, so a 50 ml tube goes faster than you'd expect once you're applying enough.

Traveling With Your Skincare

Most countries limit liquids in cabin baggage to 100 ml per container. The 30–50 ml sizes travel comfortably; 150 ml and above needs to go in checked luggage. Decanting into smaller bottles works in a pinch, but products keep best in their original packaging.

Still Unsure?

Every product page shows the exact size in the product title and in the SIZE selector. If you'd like a recommendation for your routine, contact us — we're happy to help.

Care Guide Care Guide

Introducing our 2-step eyebrow perm kit, complete with a brush, designed for the perfect balance of effectiveness and gentleness.

Achieve effortless eyebrow lifts at home with our easy-to-use self-perming system.

1st step: Softening lotion smoothens and softens the eyebrow hair.

2nd step: Neutralizing lotion neutralizes the softened eyebrow hair.

1, 2 steps in one box for the first all-in-one eyebrow lift perm kit at home.

Using the hole, dip and pull out a large amount of 1,2 step lotion. Using a fine and soft brush, brush and organize eyebrow hair to your preferred direction. Exclusively selected one RIGHT brush out of countless brushes. We've tried to match with ENTROPY eyebrow lift perm formula.

Q. How many uses are available per box?
A. Depending on the amount used, it can be used an average of 5-6 times.

Q. How long does it last?
A. Depending on the amount used, it lasts an average of 2-3 weeks. With proper grooming and nourishment (using Brow and Lash Booster Serum), it can last up to 4 weeks.

Q. When can I reuse it?
A. To minimize damage, it is recommended to wait at least 2 weeks before the next treatment.

Q. I have sensitive skin, is it okay to use?
A. Tough Brow Lift Perm is certified for low irritation in skin irritation tests. However, depending on individual skin characteristics, there may be allergic/sensitive reactions, so it is recommended to check the ingredients beforehand and conduct a patch test before use.

Q. Can I use it if I'm pregnant/breastfeeding?
A. Tough Brow Lift Perm has completed skin irritation tests, but since it contains perm ingredients, sensitive use during pregnancy/breastfeeding is not recommended.

Q. The content of Step 1 is pink, is it defective?
A. This is a natural phenomenon caused by slight air contact during the product manufacturing process. It does not affect the product's effectiveness or efficacy, so please use it with confidence.

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.
