Overview on nanotechnology based cosmeceuticals to prevent skin aging

Skin aging is an inevitable process and the highest contributing factor to this process is the effect of ultraviolet rays. However, nutrients, dry skin, smoking, hormones and gravity are also other important factors. Skin aging is classified as intrinsic (chronological) and extrinsic (photo-aging). Generally, in aged skin, effects such as thinning, loss of elasticity, spotting, wrinkles and sagging are observed. There are various approaches to preventing skin aging. The most widely used age combating substances in cosmeceuticals are kinetin, retinoids, sun filters, herbal ingredients (such as resveratrol, turmeric, and green tea), and antioxidants (such as alpha-tocopherol, ascorbic acid, coenzyme Q10 and lipoic acid). In recent years, these molecules have been formulated as nanosized carriers such as vesicular systems, polymeric and lipid nanoparticles, nanoemulsions, dendrimers, and fullerenes. Novel carrier systems have a lot of advantages when compared to conventional formulations. In this review, an overview of cosmetic, product-oriented solutions for skin aging is given and different approaches to combat aging are summarized.
