Niacinamide (vitamin B3) is a water-soluble active that supports the skin barrier, regulates sebum, brightens hyperpigmentation, and reduces inflammation. It is widely tolerated across skin types and used in concentrations commonly ranging from 2% to 10%.
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.
Myrciaria Dubia (camu camu) fruit extract is derived from an Amazonian fruit exceptionally rich in vitamin C and polyphenols, used in topical formulations for its antioxidant and skin-brightening properties. It may help neutralize free radicals and support a more even skin tone.
Acerola fruit extract is derived from the West Indian cherry and is rich in vitamin C (ascorbic acid) and polyphenols, used in topical formulations for its antioxidant and brightening properties. It may help neutralize free radicals and support skin tone, though stability of its natural vitamin C content can vary.
Dipotassium glycyrrhizate is a water-soluble salt derived from licorice root (glycyrrhizic acid) used in skincare for its anti-inflammatory, soothing, and antioxidant properties. It is commonly added to formulations to calm irritation, redness, and sensitivity.
Camellia Sinensis Leaf Extract (green tea extract) is derived from the leaves of the tea plant and is rich in polyphenols, particularly catechins like EGCG. It is used in skincare for its antioxidant, anti-inflammatory, and soothing properties.
