29 of 29 explained

Water/Aqua/Eau 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.

3-O-Ethyl Ascorbic Acid (8.5%) antioxidant

3-O-Ethyl Ascorbic Acid is a stable vitamin C derivative that skin converts to ascorbic acid. It survives in a formula far better than pure vitamin C and works at a gentler pH, so it suits skin that finds the pure acid uncomfortable.

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.

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.

Caprylic/Capric Triglyceride emollient

Caprylic/Capric Triglyceride is the light fraction of coconut oil, with the heavy parts removed. It is the workhorse emollient of modern formulas: it softens skin, dissolves oil-soluble actives and absorbs without the greasy weight of a whole plant oil.

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.

Methyl Trimethicone silicone

Methyl Trimethicone is a light, volatile silicone chosen for a notably dry finish. It thins a formula and disperses powders evenly.

Hydrogenated Poly(C6-14 Olefin) emollient

Hydrogenated Poly(C6-14 Olefin) is a synthetic hydrocarbon emollient. It gives a smooth, silicone-like glide and is completely stable, so it does not go rancid.

Pentaerythrityl Tetraethylhexanoate emollient

Pentaerythrityl Tetraethylhexanoate is a light ester emollient that gives a dry, silky finish and disperses pigment evenly.

Cetearyl Olivate emulsifier

Cetearyl Olivate is the water-loving half of the olive-derived emulsifier pair. With sorbitan olivate it builds emulsions whose lipid profile is close to skin's own.

Potassium Cetyl Phosphate emulsifier

Potassium Cetyl Phosphate is an emulsifier prized for keeping powdered ingredients evenly suspended, which is why tinted and mineral-powder textures use 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.
