Overview of Nanocosmetics with Emphasis on those Incorporating Natural Extracts

The document provides a comprehensive overview of nanocosmetics, particularly those incorporating natural extracts, highlighting their potential applications and benefits. It discusses the use of nanosized particles to enhance the delivery and effectiveness of active ingredients in cosmetic products, such as moisturizers, sunscreens, and hair care formulations. These particles offer benefits like sustained release, increased reactivity, and improved solubility. However, concerns about potential toxicity and environmental impact are noted, with some nanoparticles showing minimal DNA damage in studies. The review emphasizes the need for further research to understand the health and environmental implications of nanocosmetics and outlines current regulatory guidelines for their production. Additionally, it highlights the trend towards sustainable and eco-friendly cosmetics, using natural ingredients like essential oils and vegetable oils, which provide antioxidant and photoprotection benefits.
