21 of 21 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.

Malpighia Emarginata (Acerola) Fruit Extract plant extract

Acerola cherry extract. The fruit is one of the richest natural sources of vitamin C, and the extract is used as an antioxidant botanical.

Propanediol humectant

Propanediol is a plant-derived glycol used in place of propylene glycol. It hydrates, carries actives into solution, and gives a lighter, less sticky slip than glycerin at the same strength.

Alcohol Denat solvent

Alcohol Denat. is ethanol with a bitter additive that makes it undrinkable, which is a tax rule rather than a formulation choice. It behaves like alcohol: a fast-evaporating solvent that gives a weightless finish and can feel drying at higher levels.

Euterpe Oleracea Fruit Extract plant extract

Acai fruit extract, from the Amazonian palm berry. It carries anthocyanins, the same purple pigment polyphenols found in blueberry, and is used as a plant antioxidant.

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.

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.

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.

PEG-60 Hydrogenated Castor Oil emulsifier

PEG-60 Hydrogenated Castor Oil is a castor-oil-derived solubiliser. It is what keeps fragrance and oil-soluble ingredients dissolved in a watery formula so it stays clear.

Bis-PEG-18 Methyl Ether Dimethyl Silane silicone

A water-soluble silicone used for a light, silky slip without an oily film. It also helps other ingredients spread evenly.

Ethylhexylglycerin preservative booster

Ethylhexylglycerin softens skin and boosts a preservative system, which is why it is nearly always sitting beside phenoxyethanol or 1,2-hexanediol. It also cuts down the odour bacteria produce, so it turns up in deodorising products.

Adenosine active

Adenosine is a nucleoside that Korea's own cosmetic authority recognises as a wrinkle-care functional ingredient, which is why it appears on so many Korean lists at a low level. It is used for the look of fine lines and is stable and well tolerated.
