Nicotinamide (B3) 4% in Hyaluronic Acid Serum 50ml (Oil free for acne and rosacea)
The levels of Vitamin B3-dependent coenzymes in the skin can decrease with age, and topical nicotinamide appears to reverse the decline. Several studies have shown that topical nicotinamide improved fine lines and wrinkles, hyperpigmented “age” spots, red blotchiness, and skin sallowness (yellowing) as well as elasticity (11). One study showed nicotinamide to increase the skin’s production of ceramides (natural emollients and skin protectants) and therefore improving skin hydration (12). Another study reported improvement of eyelid wrinkles after 8 weeks of application of a cosmetic containing 4% nicotinamide (13).
