Nanotechnology is an advanced technology that involves working with particles at nanometer scale with structure size being 100 nanometers or smaller. Particles less than 1000 nanometers are known to change, and implementation of these properties can help create products with enhanced application. It signifies the evolving area of research and development, concerned in delivering innovative solutions to increase the efficacy of a product.
In cosmeceuticals, nanotechnology has played an important role. Using new techniques to manipulate matter at an atomic or molecular level, they have been at the root of numerous innovations, opening up new perspectives for the future of cosmeceutical industry. The most common designed platform included micelles, polymeric micelles, dendrimer, liposomes niosomes, ethosomes, glycosomes nanoparticles and nanocapsules. Smaller particles can be more readily absorbed into the skin to optimize the delivery of functional ingredients into the skin and enable these materials to reach the action site quicker because Nanoparticles are also proficient in modifying the flux, targeting the drug to the location, tailoring the size of drug and in making the stratum corneum permeable in a selective manner. Examples of using nanotechnology for herbal extract in cosmeceuticals are the use of Phyllanthus emblica exacts in anti-aging products.
Functional ingredients of anti-aging are retinol, vitamin C, microcollagen, herb extracts with antioxidant activities i.e. curcumin, Phyllanthus emblica extract, Centella asiatica extract etc. Examples of inorganic nanoparticles used in sunscreen are titanium dioxide and zinc oxide nanoparticles, since they protect the skin by reflecting ultraviolet radiation. Difference in size and surface coating can be utilized to alter surface properties of nanoparticles that help enhance biological safety. Anti-ultraviolet radiation of herbal extract can be used instead of inorganic compounds for better benefits. The nanotechnology-based delivery techniques have proved to offer advantages of greater stability, higher efficacy and have also been reported to show prolonged effects.
