Authentic K-Beauty

Sourced from official Korean suppliers, date-checked before packing.

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

Q. How many uses are available per box?

A. Each box contains 6 packets of powder and 1 tube of cream. Since one packet of powder is measured for one use, you can use it a total of 6 times.

Q. How long does the color last after one dyeing session?

A. On average, the color lasts for about 4 weeks after one use. It is recommended not to perform other dyeing/perming treatments during this period.

Q. How can I adjust the color myself?

A. From a soft brown color to a light golden brown, the hair color will lighten within approximately 1 minute after applying brow bleach. However, the lightening effect may vary depending on individual hair condition, thickness, time, and temperature, so we recommend performing a patch test on a small, inconspicuous area of hair before use.

Q. Can I use it on sensitive skin?

A. Brow bleach has undergone skin irritation tests and is suitable for sensitive skin. We have carefully considered even sensitive skin types.

Ingredients

Ammonium Persulfate, Sodium Silicate, Potassium Persulfate, Sodium

How to Use

Cut 1st powder of 1 product with scissors and pour it into the lid of the 2nd product cream.
At this time, be extra careful not to let the powder fly into your eyes.

Pump the second cream to the star mark on the lid and mix it in the ratio of 1(powder) : 3(cream).

When mixing the 1st and 2nd agents, mix them using a cotton swab or mix them well with the included eyebrow comb.

At this time, the eyebrow comb can be used multiple times, so please wipe it clean after using it and store it.

The part marked on the lid is the average capacity recommended for entropy makeup to be used once,

and we recommend you to increase or decrease the capacity according to your hair.

Bleach it on the area you want and apply it for about a minute.
(If you have sensitive skin, coat the area with Vaseline or lip balm.)

CAUTION!! At this time, bleaching colors by time may vary depending on individual simulation, thickness, neglect time, and temperature, so we recommend that you test the ends of invisible hair before bleaching and check the bleaching time that suits you.

TIP Apply enough to the inside so that the tip of the eyebrow simulation (hair root) can be bleached.

After about a minute, remove the cream lightly and check the color of your bleached eyebrows. If the color you want comes out, wipe it clean with a wet tissue. If it's not completely bleached, leave it a little longer and wipe it clean.
(At this time, do not exceed the maximum time of 3 minutes. Please be extra careful not to get it in your eyes when wiping off.)

Use a multi-use eyebrow comb to tidy up your eyebrows.

It lasts up to 4 weeks for one use, and we recommend that you use it 4 weeks apart from all other treatments, including re-treatment or eyebrow lift perm. If you apply simulated moisture and nutrition with Brow & Lash Booster Serum after using the product, you can take care of it more healthily.

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.
