42 of 55 explained

Butylene Glycol humectant

Butylene Glycol is a small glycol that does two jobs at once: it holds water in the top layer of skin and it dissolves plant extracts and actives that plain water cannot. It also thins a formula, which is why watery Korean essences lean on it.

Glycerin humectant

Glycerin is the most used humectant in skincare. It draws water into the outer layer of skin and holds it there, and it is one of the very few ingredients whose hydrating effect is settled science rather than marketing. Higher amounts feel tacky, which is why it is usually blended.

1,2-Hexanediol humectant

1,2-Hexanediol is a glycol used for two reasons: it holds water like glycerin, and it makes a formula harder for microbes to live in, so less traditional preservative is needed. Korean formulas use it heavily for that second reason.

Niacinamide active

Niacinamide is vitamin B3, and it is the most studied active in Korean formulation. It is used at roughly 2 to 5 percent for the look of uneven tone and visible pores, and it is water soluble, stable and comfortable beside almost every other active, which is why it turns up in so many lists.

Dibutyl Adipate emollient

Dibutyl Adipate is a light ester emollient used as a solvent for UV filters and pigments and to keep a formula from feeling tacky.

Hydrogenated Lecithin emulsifier

Hydrogenated Lecithin is lecithin with its unsaturated bonds filled in, which makes it far more stable. It emulsifies and is the standard shell for the liposomes that carry actives into the outer layer of skin.

Caprylic/Capric Triglyceride emollient

Caprylic/Capric Triglyceride is the light fraction of coconut oil, with the heavy parts removed. It is the workhorse emollient of modern formulas: it softens skin, dissolves oil-soluble actives and absorbs without the greasy weight of a whole plant oil.

Carthamus Tinctorius (safflower) Flower Extract plant extract

Safflower Flower Extract is a traditional East Asian dye and skincare plant. It is used as a conditioning antioxidant extract and can tint a formula.

Dextrin thickener

Dextrin is a starch fragment used to thicken and to give a formula a light, powdery finish. It is also a common carrier for powdered extracts.

Limonene fragrance component

Limonene is the citrus-peel aromatic. It appears here because EU labelling requires 26 fragrance components to be named individually rather than hidden inside "fragrance", and it is one of them.

Ammonium Acryloyldimethyltaurate/Vp Copolymer thickener

This is a synthetic thickener that gels quickly and holds an emulsion stable across a wide pH range. It gives a light, non-tacky body.

Xanthan Gum thickener

Xanthan Gum is a polysaccharide made by fermenting sugar. It thickens a watery formula into a gel and holds the whole thing in suspension so nothing separates. Too much of it and a serum turns stringy, which is why it appears in fractions of a percent.
