32 of 39 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.

Cyclopentasiloxane silicone

Cyclopentasiloxane is a volatile silicone: it spreads a formula thin and smooth then evaporates, leaving no residue. It is the silicone behind a dry, powdery primer finish.

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.

Cetearyl Alcohol fatty alcohol

Cetearyl Alcohol is a waxy solid, not the drying kind of alcohol. It is a blend of cetyl and stearyl alcohols used to thicken a cream and keep oil and water from separating, and it softens skin as it does so.

Dimethicone silicone

Dimethicone is the most used cosmetic silicone. It forms a breathable film that smooths the surface, slows water leaving skin, and gives the slip that makes a primer or cream feel silky. It is inert and does not penetrate.

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.

Glyceryl Stearate emulsifier

Glyceryl Stearate is glycerin joined to stearic acid, and one of the most used emulsifiers in skincare. It holds oil and water together and thickens the result, and it softens skin at the same time.

Dimethiconol silicone

Dimethiconol is a high-molecular-weight silicone that leaves a longer-lasting smooth film than dimethicone. It is used for lasting slip and shine.

Hydroxyethylcellulose thickener

Hydroxyethylcellulose is a cellulose thickener that builds a clear, smooth gel and holds the rest of the formula in suspension.

Ricinus Communis (Castor) Seed Oil emollient

Castor Oil is thick, glossy and unusually good at dissolving pigment, which is why it dominates lip and cleansing-balm formulas. It is a heavy emollient.

Hydroxyethyl Urea humectant

Hydroxyethyl Urea is a humectant that holds a lot of water for its size and stays comfortable at high levels. It is used where a formula needs to feel deeply hydrating without oil.

Melia Azadirachta Flower Extract plant extract

Melia Azadirachta is neem. Its leaf and flower extracts are long-standing Ayurvedic ingredients, and Korean formulas use them in products aimed at the look of congested, blemish-prone skin.
