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%.
Oryza Sativa (Rice) Lees Extract is derived from the sediment (lees) left after rice fermentation, containing amino acids, vitamins, and antioxidants. It is used in skincare to moisturize, brighten, and provide antioxidant conditioning benefits to the skin.
Leontopodium alpinum (Edelweiss) extract is a plant-derived ingredient rich in antioxidant compounds such as leontopodic acid and chlorogenic acid, used in skincare for its free-radical scavenging and soothing properties. It is often included in anti-aging and protective formulations.
Adenosine is a nucleoside that signals through cell-surface receptors to promote dermal fibroblast activity and collagen/elastin production, helping reduce the appearance of fine lines and wrinkles. It also has anti-inflammatory and soothing properties at low concentrations commonly used in cosmetics (around 0.04-0.1%).
