Abstract
Skin aging is a complex biological process influenced by intrinsic factors such as genetics and hormonal changes as well as extrinsic factors including ultraviolet radiation, pollution, and lifestyle habits. In recent years, anti-aging cosmetics have evolved from simple moisturizers to scientifically formulated cosmeceuticals containing bioactive compounds with demonstrated biological activity. Key ingredients such as peptides, retinoids, antioxidants, hyaluronic acid, plant polyphenols, and probiotic extracts have shown promising effects in reducing wrinkles, improving skin elasticity, and enhancing hydration. Advances in nanotechnology, biomimetic formulations, and delivery systems have improved penetration and stability of these actives. Clinical studies increasingly support the efficacy of certain compounds, particularly retinoids, vitamin C, peptides, and botanical antioxidants, although robust long-term trials remain limited. This review discusses recent developments in anti-aging cosmetics, focusing on bioactive ingredients, mechanisms of action, clinical effectiveness, and future research directions in cosmetic dermatology.
