What's in your box

You've been told to read the label.
Nobody told you how.

That wall of Latin on the back of a Korean bottle isn't hiding anything from you. It's a document with rules — and there are only four of them. Learn those, and you can read any product on any shelf in any country. Then we'll walk you through every ingredient in your Bundle, in plain English.

A calm arrangement of skincare textures in warm daylight, setting the tone for gentle Korean skincare
a dozen

You don't need to learn 1,800 ingredients. You need four rules, and a dozen or so ingredients — the ones actually in your Bundle.

Start here

Four rules, and the label opens up.

Every ingredient list in the world — Korean, French, American — is written in the same system. It's called INCI: the International Nomenclature of Cosmetic Ingredients. One official name per ingredient, identical on every label, in every country, regardless of the language on the rest of the box. That's the part people miss. The scariest-looking panel on a Korean bottle is the one part that's already in your language.

1

Order is concentration.

Ingredients are listed most-to-least. The first five to seven make up the bulk of what's actually in the bottle. If an ingredient is on the front of the box but tenth on the back, you now know what that means.

2

There's a line where order stops mattering.

Below one percent, ingredients can be listed in any order — and so can fragrance and colorants. So the bottom third of a list isn't ranked. The usual tell for where the line falls: it's around where preservatives, thickeners and pH adjusters start showing up.

3

Latin means plant, not chemical.

INCI names botanicals by their species. Shea butter is Butyrospermum Parkii Butter. Green tea is Camellia Sinensis Leaf Extract. Latin on a label isn't a chemist — it's a botanist.

4

A scary name is usually a familiar thing.

Sodium Hyaluronate is hyaluronic acid. Tocopherol is vitamin E. Niacinamide is vitamin B3. Aqua is water. The formal name and the friendly name are the same ingredient.

The part nobody explains

Four things a Korean label does that an American one doesn't.

Korean cosmetics are regulated by the Ministry of Food and Drug Safety, and the rules are specific in ways that matter to you — especially if your worry is irritation. None of this is on the box in English. Here it is.

Korea makes brands name fragrance allergens. The US doesn't.

Korean companies are required to list 25 recognized fragrance allergens within the full-ingredient section once they pass certain concentrations. In the US, the 2022 MoCRA law calls for fragrance allergen disclosure, but the FDA hasn't yet issued the regulations that would put it into effect. If you react to fragrance, a Korean label is often telling you more than the American one sitting next to it.

"Functional cosmetic" is a legal filing, not a marketing word.

Certain claims in Korea — brightening, anti-wrinkle, sun protection — require the product to be registered as a 기능성화장품 (gineungseong hwajangpum, "functional cosmetic"), and the label has to carry that word or the MFDS symbol. The claim was reviewed by a regulator. Compare that to "clean," "natural," and "dermatologist-approved" in the US, which mean whatever the brand wants them to mean, because no one regulates them.

A short list on a small bottle isn't a short formula.

Korean law lets products of 50ml or under skip most of the ingredient list — everything except colorants, gold leaf, fruit acids, the actives behind a functional claim, and anything with a regulated blending limit. So a 30ml ampoule may show you six ingredients when it contains thirty. It isn't hiding something, and it isn't "cleaner." It's a packaging rule.

Every ingredient must be listed in descending order — by law.

That first rule you just learned isn't a courtesy. It's written into Korea's cosmetics regulation, with the one-percent exception written in alongside it. Which means the order on the back of a Korean bottle is information you can actually rely on.

Two minutes

Let's read a real one together.

This is the actual, unedited ingredient list from the Low pH Good Morning Gel Cleanser in your Bundle. Twenty-five ingredients. Here's what you'd notice, in order.

1 The product · positions 1–5

Water · Cocamidopropyl Betaine · Sodium Lauroyl Methyl Isethionate · Sodium Chloride · Polysorbate 20

2 The botanicals · positions 6–14

Styrax Japonicus Branch/Fruit/Leaf Extract · Butylene Glycol · Saccharomyces Ferment · Cryptomeria Japonica Leaf Extract · Nelumbo Nucifera Leaf Extract · Pinus Palustris Leaf Extract · Ulmus Davidiana Root Extract · Oenothera Biennis (Evening Primrose) Flower Extract · Pueraria Lobata Root Extract

Somewhere around here — one percent

3 Actives & housekeeping · unranked

Melaleuca Alternifolia (Tea Tree) Leaf Oil5 · Allantoin · Caprylyl Glycol · Ethylhexylglycerin · Betaine Salicylate4 · Citric Acid · Ethyl Hexanediol · 1,2-Hexanediol · Trisodium Ethylenediamine Disuccinate · Sodium Benzoate · Disodium EDTA

1

The first five are the whole product. Water, then two cleansing agents, then salt, then a helper that lets oil and water mix. That's a gel cleanser: water and mild surfactants. Sodium Lauroyl Methyl Isethionate is one of the mildest cleansing agents in use. And Sodium Chloride is table salt — it's there to turn a runny liquid into a gel. Rule four in action: a chemical-sounding name doing an unglamorous job.

2

Positions six through fourteen are a garden. Styrax Japonicus. Nelumbo Nucifera. Ulmus Davidiana. Pueraria Lobata. Lotus leaf, elm root, kudzu root, Japanese snowbell. Rule three: Latin means plant. Ulmus Davidiana in particular is a traditional Korean and Chinese medicinal root, and it turns out to be a genuinely good moisturizer with anti-inflammatory properties. This is the hanbang thread, sitting quietly in the middle of a drugstore cleanser.

3

Then the line — and everything after it is unranked. You can see roughly where one percent falls: it's where the preservatives, the chelators, and the pH adjusters start appearing. Sodium Benzoate, Disodium EDTA, Citric Acid — these are housekeeping. They keep the product from spoiling and hold it at the right pH. Below this line, order tells you nothing about amount.

4

The active is below the line, and that's the point. Betaine Salicylate is the BHA — the pore-clearing exfoliant. It sits at position nineteen, under one percent. That is not a flaw. This is a cleanser you use every morning; a strong exfoliant near the top would be a product that asks something of your skin daily. Betaine Salicylate is also the gentler form: pure salicylic acid is limited to tiny amounts under Korean regulation, so K-beauty uses this instead, and it's roughly half as strong — a 4% betaine salicylate formula behaves like a 2% salicylic acid one.

5

And there's an essential oil in here. Here's where it sits. Melaleuca Alternifolia — tea tree oil — is at position fifteen, just under the line. It's the reason this cleanser works on breakouts: tea tree oil is one of the best-established anti-acne ingredients there is, and studies put a 5% gel in the same range as benzoyl peroxide.

It's also an essential oil, which is the category we told you to scan for. It sits on the mild end of that category — it carries only small amounts of the common fragrance allergens, which is why reviewers who are generally hard on essential oils make an exception for it. And it's below the one-percent line, in a product you rinse off. If tea tree is something you already know your skin doesn't like, now you know it's here.

That's what reading a label is actually for. Not to find a product with nothing in it — to find out what's in the one you're holding, and decide for yourself.

Now do it again on any bottle you own. That's the whole skill. And if you want to check us, here's where to do it.

Why it works

Chosen to work together.

Every bundle is a handful of products picked to layer without fighting each other — a hydrator that preps, a treat step that plumps, a gentle retinal where lines show first, a barrier cream that makes everything else feel gentler, and daily SPF to protect the work. On their own, they're good ingredients. Together, in the right order, they're a habit that holds. The box is the product — these ingredients are why it works as one.

For sensitive skin

What to look at first, if you're afraid of reacting.

If you've had a bad reaction before, you don't read a label front to back. You scan it. Here's the order to scan in.

Fragrance, first — wherever it sits.

Look for Parfum, Fragrance, Aroma, and any essential oil. And check for them even at the very bottom of the list, because below one percent the order is meaningless — something can be last and still be the thing you react to.

Essential oil is not automatically the gentle option.

This is the assumption worth unlearning. Fragrance allergens turn up in natural extracts and essential oils just as readily as in synthetic fragrance — lavender, citrus and ylang-ylang oils are among the most common triggers on the recognized allergen lists. "Natural" describes where an ingredient came from. It says nothing about whether your skin will like it.

And yes — there's an essential oil in one of your own products. It's the tea tree oil in the morning cleanser, and we walked through exactly what it is and where it sits, up here.

Alcohol, but only high up.

Alcohol Denat. in the top five can feel drying on already-sensitive skin. Further down, or as Cetearyl Alcohol or Stearyl Alcohol — different ingredients entirely, and those two are softening, not drying.

Where the actives sit.

A strong acid or retinoid in the top five is a product that will ask something of your skin. The same ingredient below the one-percent line is a supporting player. Same name, different experience.

And two things that aren't true:

A short list isn't automatically gentler. A long list isn't automatically harsher. What matters is what's in the top five and whether anything in there is something you personally react to.

Which is the honest answer to the question underneath all of this: nobody can promise you won't react to something. What we can do is tell you exactly what's in the bottle, teach you to read it, and point you at someone independent to check us.

What to expect

Honest about pace.

Good skincare is a habit, not a quick fix — here's roughly what to expect.

Week 2

Skin feels more comfortable and hydrated. The first thing you notice is usually how it feels, not how it looks.

Week 4

Tone starts looking more even and skin looks calmer. Give it about four weeks of consistent use — this is where most people see their skin settle.

Week 8

Fine lines look softer and skin looks more resilient. The slow, real results show up here — and they last because the habit does.

The heritage thread

Some of this isn't new at all.

Ginseng and artemisia have been part of Korean skincare — hanbang — for centuries. The tradition knew what it had; modern science just explains why it worked. That's the quiet thread running through everything we chose.

A small vocabulary

Nine Korean words worth recognizing.

If the English side of the box runs out, these are the words that carry the information.

전성분

jeon-seongbun

full ingredient list

Literally "all ingredients." If you find this heading, everything after it is the complete list.

기능성화장품

gineungseong hwajangpum

functional cosmetic

A regulated designation, not a marketing phrase. Brightening, anti-wrinkle and sun-protection claims require it.

사용기한

sayong-gihan

use-by date

How long the product is good for, unopened.

개봉 후 사용기간

gaebong-hu sayong-gigan

period after opening

The other kind of date — how long once you've opened it. Korean labels using this one must also print the manufacture date.

착향제

chakhyangje

fragrance agent

The word to look for if fragrance is your concern.

무향

muhyang

fragrance-free

No fragrance added. Worth knowing the difference from the next one.

저자극

jajageuk

low-irritation

A claim about mildness, usually backed by a patch or clinical test.

보존제

bojonje

preservative

Present in nearly everything with water in it, and that's a good thing — it's what keeps a wet product from growing something.

정제수

jeongjesu

purified water

The first ingredient in most of what you own.

How we chose

Gentle first, and made to work together.

We didn't pick the flashiest ingredients — we picked the ones that are gentle first, and that work together as a habit. Everything in your bundle was chosen to be effective without asking your skin to tough anything out. Curated, gentle, and tested as a whole.

And we'd rather you check than trust us. Every ingredient above is on the label of a product you can look up yourself, on a site we don't own.
