Overview on nanotechnology based cosmeceuticals to prevent skin aging

Abstract

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.
