Effectiveness of Topical Niacinamide for Anti-Aging
Topical Niacinamide, a form of vitamin B3, has been highlighted as a promising cosmaceutical ingredient for anti-aging. While limited placebo-controlled studies exist in cosmetic research, Niacinamide has shown efficacy in reducing wrinkles, blotchiness, and hyperpigmented spots in aging skin. In a 12-week study on middle-aged women, a 5% Niacinamide formulation demonstrated a 5% reduction in wrinkles and fine lines, along with improvements in skin elasticity, without reported skin irritation.
