43 of 46 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.

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.

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.

Glycereth-26 humectant

Glycereth-26 is a modified glycerin that hydrates with far less stickiness than glycerin itself. It is a common way to load water into a formula that has to stay light.

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.

Melaleuca Alternifolia (Tea Tree) Leaf Extract (2,000 ppm)* plant extract

Tea Tree Leaf Extract is the water-based extract rather than the essential oil, so it is far milder and much less aromatic. It is used in formulas for blemish-prone skin.

Caprylyl Glycol preservative booster

Caprylyl Glycol is a glycol that conditions skin and, more importantly, strengthens a preservative system so less of the traditional preservative is needed. It appears in most modern formulas built without parabens.

Polyglyceryl-10 Laurate emulsifier

Polyglyceryl-10 Laurate is a sugar-derived emulsifier and solubiliser, mild enough to be a standard choice in Korean essences. It dissolves small amounts of oil into water without any tightening feel.

Hydroxyacetophenone preservative booster

Hydroxyacetophenone is an antioxidant that also strengthens a preservative system, so a formula needs less traditional preservative. Korean formulas pair it with 1,2-hexanediol constantly.

Polyglyceryl-4 Laurate emulsifier

A short polyglycerin ester used as a mild emulsifier and cleansing agent. It is common in balms designed to melt on skin and then rinse away.

Betaine humectant

Betaine is a sugar-beet-derived humectant that cells use to hold water. In a formula it hydrates and takes the edge off cleansers and acids, which is why it often appears alongside them.

Trehalose humectant

Trehalose is a sugar that some desert plants use to survive drying out. In skincare it is a humectant that holds water in the outer layer and helps a formula feel comfortable rather than tight.
