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%.
Retinol is a vitamin A derivative that converts to retinoic acid in the skin, promoting cell turnover and stimulating collagen synthesis. It is widely used to address fine lines, photoaging, and acne.
