3-O-Ethyl Ascorbic Acid is a stable, water-soluble ethylated derivative of vitamin C that converts to ascorbic acid in the skin, providing antioxidant protection and supporting collagen synthesis and pigmentation control. It is valued for greater stability than pure L-ascorbic acid while delivering similar brightening and anti-aging benefits.
Tetrahexyldecyl Ascorbate is a stable, oil-soluble derivative of vitamin C used as an antioxidant that can be converted to ascorbic acid in the skin, supporting collagen synthesis and helping reduce signs of photoaging and hyperpigmentation. It is favored for its stability and ability to penetrate the skin's lipid barrier compared with pure ascorbic acid.
Gluconolactone is a polyhydroxy acid that gently exfoliates the skin surface, provides antioxidant and humectant benefits, and is often considered milder than alpha hydroxy acids. It is well tolerated, including by sensitive skin, due to its larger molecular size and slower penetration.
Ilex Paraguariensis (yerba mate) leaf extract is a plant-derived ingredient rich in polyphenols, caffeine, and xanthines, used in skincare for its antioxidant and skin-conditioning properties. It may help protect against oxidative stress and is sometimes included in formulations for its potential soothing and toning effects.
Ilex Guayusa Leaf Extract is derived from an Amazonian holly plant and is rich in caffeine, chlorogenic acids, and polyphenols. In skincare it is used primarily for its antioxidant and protective properties against free radical and environmental damage.
Magnesium Ascorbyl Phosphate is a stable, water-soluble derivative of vitamin C used as an antioxidant and skin-brightening active. It is converted to ascorbic acid in the skin, supporting collagen synthesis and reducing hyperpigmentation.
