25 of 25 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.

Propylene Glycol humectant

Propylene Glycol is a small glycol used as a humectant and solvent. It hydrates and helps actives dissolve; newer formulas often swap it for propanediol, which does the same job with a lighter feel.

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.

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.

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.

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.

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.

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.

Dipotassium Glycyrrhizate active

Dipotassium Glycyrrhizate is a water-soluble salt derived from licorice root. It is the licorice fraction Korean formulas use for the look of redness, and it is far more stable in water than the whole extract.

Xylitylglucoside humectant

Xylitylglucoside is a sugar-derived humectant, the third member of the xylitol blend. Together the three hold water in the outer layer for longer than any of them does alone.

Anhydroxylitol humectant

Anhydroxylitol is a xylitol derivative used as a humectant. It is almost always part of the xylitol, anhydroxylitol and xylitylglucoside blend sold as a moisture-retention complex.
