Niacinamide (Vitamin B3) is a multifunctional ingredient widely used in skincare and haircare formulations for its broad benefits. In haircare, it supports stronger strands by increasing keratin production, improving scalp circulation, and promoting healthier follicle growth. In skincare, Niacinamide helps boost the production of natural emollients, supporting hydration and barrier function. It is also a popular ingredient in brightening products, as it reduces hyperpigmentation and offers a gentler alternative to harsh chemical lighteners.
