NANOEMULSION: A NOVEL TRAIT IN THE TREATMENT OF SKIN AGEINGAbstract
Nanoemulsion system is a promising vehicle due to the powerful ability to deliver the drug through the skin. Researchers have been conducted to prove its potential for the delivery of the drugs used in many skin disorders. Skin is the largest organ and acts as the first line of defense of our body. After a certain period of time, our skin loses tone and elasticity which is called aging. It is the result of programmed senescence and prolonged environmental injury to the skin. The aim of this review article is to provide information regarding the control of skin aging by the nanoemulsion drug delivery system. Novel carrier systems have a lot of advantages when compared to conventional formulations. 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, Therefore, nanocarrier such as liposomes, noisome, microemulsions and nanoparticles have been widely investigated as delivery systems for antioxidants to improve their beneficial effects in the treatment of skin aging. In this review, an overview of cosmetic, product-oriented solutions for skin aging is given and different approaches to combat aging are summarized. This review discusses the role of oxidative events of tissue degeneration and aging in general, and for the skin in particular. The mechanisms involved in intrinsic and extrinsic (photo-) aging are described. To prevent or treat skin aging, topical supplementation with antioxidants is regarded as one of the most promising strategies. Overall review says that antioxidants are most commonly used in anti-aging cosmetic products will be reviewed along with the nanocarrier designed to improve their safety and effectiveness.
