From the Research
Topical niacinamide is a highly effective treatment for skin aging, with the most recent and highest quality study 1 demonstrating its ability to reduce fine lines, wrinkles, and hyperpigmentation, while improving skin elasticity and firmness. The use of topical niacinamide for skin aging is supported by multiple studies, including a 2024 review 1 that highlights its mechanisms of action, including increasing ceramide and fatty acid levels in the skin, antioxidant properties, and stimulation of collagen production. Key benefits of topical niacinamide include:
- Reduction in fine lines and wrinkles
- Improvement in skin hyperpigmentation
- Enhancement of skin elasticity and firmness
- Antioxidant properties that protect against environmental damage
- Inhibition of the transfer of melanin to skin cells, which helps fade dark spots
- Suitable for all skin types, including sensitive skin
- Can be safely combined with other active ingredients like retinoids and vitamin C for enhanced anti-aging benefits. According to the study 1, niacinamide has been shown to be well-tolerated and safe for use in cosmetics, with no convincing evidence of specific molecular targets for controlling skin aging and pigmentation. The recommended concentration of topical niacinamide is typically between 2-10% in serums and moisturizers, applied once or twice daily to clean skin before heavier moisturizers and sunscreen, with noticeable improvements seen after at least 8-12 weeks of use 2, 3.
