37 of 37 explained

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.

Dipropylene Glycol humectant

Dipropylene Glycol is a glycol used as a solvent and a light humectant. Its main job is keeping the rest of the formula dissolved and the texture fluid rather than adding hydration of its own.

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.

Artemisia Princeps Leaf Extract plant extract

Artemisia Princeps is Korean mugwort, one of the country's oldest skincare and bathing plants. Its leaf extract is used for the look of reddened, reactive skin, and it is the ingredient behind the mugwort category.

Sodium Hyaluronate humectant

Sodium Hyaluronate is the salt of hyaluronic acid, and it is what most products labelled hyaluronic actually contain. The salt dissolves more readily and the molecule is smaller, so it sits in the outer layer of skin rather than only on top of it.

Saccharomyces Ferment Filtrate ferment

Saccharomyces Ferment Filtrate is a brewers yeast ferment filtered clear. It supplies amino acids, B vitamins and sugars, and it is one of the ferments the Korean essence category was built on.

Cynanchum Atratum Extract plant extract

Cynanchum Atratum is a root used in Korean traditional practice. Its extract is used as a conditioning plant extract in formulas for reactive skin.

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.

Sodium Heparin polysaccharide

Sodium Heparin is a sulfated sugar chain, structurally close to the heparan sulfate skin makes itself. In a formula it is a strong humectant.

Pyrus Malus (Apple) Fruit Extract plant extract

Apple fruit extract, carrying malic acid, sugars and polyphenols. It is used as a conditioning extract with a mild acid character.

Panthenol humectant

Panthenol is pro-vitamin B5: skin converts it to pantothenic acid. It is a humectant that holds water and leaves skin feeling soft and less tight, and it is one of the ingredients formulators reach for when a formula also contains something harsh.
