Nano cosmetology has applications including hair care products; make up, sunscreens and Moisturizers. Nano Cosmetics contains Liposomes and niosomes as delivery vehicles. Newer structures such as solid lipid nanoparticles and nanostructured lipid carriers have been found to perform better than liposomes. Nanostructured lipid carriers have been identified as a potential next generation cosmetic delivery agent that can boost skin hydration, bioavailability, stability of the agent and controlled occlusion. Encapsulation techniques have been proposed for carrying cosmetic actives. In cosmetic applications, nanocrystals and nanoemulsions are being investigated.
