NANOTECHNOLOGY-BASED COSMECEUTICALS FOR PREVENTION OF SKIN AGING

Skin aging is a multifactorial process caused by intrinsic factors such as genetics and extrinsic factors like ultraviolet (UV) radiation, pollution, and lifestyle. UV exposure plays a major role by generating reactive oxygen species (ROS), leading to collagen degradation, wrinkles, and loss of skin elasticity. Cosmeceuticals containing antioxidants (vitamins C and E, coenzyme Q10), retinoids, and herbal compounds such as curcumin and resveratrol help in reducing oxidative stress and improving skin structure.
However, conventional topical formulations show limitations including poor skin penetration, low bioavailability, and possible irritation. To overcome these issues, nanotechnology-based delivery systems have been developed. Nanocarriers such as liposomes, niosomes, nanoemulsions, solid lipid nanoparticles (SLN), and nanostructured lipid carriers (NLC) enhance the delivery of active ingredients by improving stability, penetration, and controlled release.These advanced systems increase therapeutic efficacy while minimizing side effects. Overall, nanotechnology-based cosmeceuticals offer a promising approach for effective prevention and management of skin aging.
