Tight, flaky or rough; little visible oil. Craves hydration + barrier support.
Ranked by hero status, breadth of documented benefit, and fit with dry skin. We rank ingredients, never specific products.
1
The ferment that made 'microbiome skincare' a shelf category. Bifida ferment lysate is a processed bacterial culture — nothing is alive by the time it reaches the bottle — used as a conditioning ingredient in essences and barrier creams.
2
The quiet workhorse of almost every Korean toner and cream. Glycerin is one of the most studied humectants in cosmetics — unglamorous on an ingredient list, but it is doing much of the hydrating you credit to fancier actives.
3
A gentle conditioning agent found in soothing Korean 'cica' and post-acne formulas. It is also one of the compounds naturally present in snail secretion filtrate, which is part of why the two show up together.
4
Amino acids do double duty in Korean routines: as humectants in essences, and as the basis of the low-pH amino-acid cleansers that replaced squeaky foaming washes.
5
A middleweight oil — richer than squalane, lighter than shea. In Korean routines it appears most in hair oils and multi-use balms.
6
Dongbaek oil is genuine Korean heritage — Jeju's camellia groves supplied it long before anyone called it skincare. It is a rich, oleic oil, so it suits dry skin far better than oily skin.
7
Coconut-derived, fractionated, and nothing like coconut oil in behaviour. It is one of the most-used emollients in cosmetics because it is light, spreads beautifully and stays fresh for years. If a Korean cleansing oil or ampoule feels silky rather than greasy, this ester is often the quiet reason.
8
The word alcohol on a label has cost this ingredient a lot of unearned suspicion. Cetearyl alcohol is a fatty alcohol — a waxy solid, closer to shea butter than to vodka — and it thickens and softens rather than dries. If a cream feels rich and stable, this is usually part of the reason.
