Prunus Persica (Peach) Fruit Extract (70%) plant extract

Peach Fruit Extract carries fruit sugars, vitamins and mild fruit acids. It is used as a hydrating extract.

Water solvent

Water is the base almost every serum, toner and cream is built on. It dissolves the water-loving ingredients and sets how light the finished texture feels. On an INCI list it is usually first, which only means it is the largest single ingredient by weight.

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.

Methylpropanediol humectant

Methylpropanediol is a small glycol used to hydrate and to help water-soluble actives penetrate the outer layer of skin more evenly. It leaves almost no tack, which suits watery textures.

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.

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.

Lactobacillus Ferment ferment

Lactobacillus Ferment is the liquid left after lactobacillus bacteria have fermented a plant or milk substrate. It carries the small molecules the fermentation produced, including lactic acid and amino acids, and is used for the look of dull, uneven skin.

Phellinus Linteus Extract plant extract

Sanghuang, a hard bracket mushroom used in Korean and Chinese herbal tradition. Its extract carries water-holding polysaccharides.

Vincetoxicum Atratum Extract plant extract

Baekmi, a traditional Korean herbal root extract. It is used as a conditioning plant extract, usually beside other Korean herbal ingredients.

Hydrolyzed Hyaluronic Acid humectant

Hydrolyzed Hyaluronic Acid is hyaluronic acid cut into much shorter fragments. The smaller the fragment, the further into the outer layer it can settle, which is why serums stack several sizes together instead of using one.

Althaea Rosea Flower Extract plant extract

Althaea Rosea is hollyhock, a mallow relative rich in mucilage. Its flower extract hydrates and leaves a cushioned, slippery feel.

Camellia Sinensis Seed Oil emollient

Oil pressed from tea seeds. It is high in oleic acid, carries some of the antioxidants of the tea plant, and is lighter in feel than most oleic oils.
