Nonetheless, further studies are needed to understand the toxic effects of nanomaterials as the side-effect-free character of cosmetic products is a significant aspect. These nanoparticles scatter UV light thereby preventing its harmful effect on the skin. Why is gut health so important for skin health? It absorbs UVR because of its semiconductive property. The various characteristics of nanomaterials such as physical, chemical, aggregation, porosity, morphology, size, solubility, and purity should be evaluated as per FDA guidelines. Another disadvantage is the difficulty in maintaining the therapeutic action in three dimensions inside the human body. Gold nanoparticles have been used for red or blue coloration; silver nanoparticles for yellowish coloration as well as gold-silver nanocomposites have been used for orange coloration [120]. Following extensive research in this area, we are confident about the superior quality and safety of thenon-nanosized ingredients used in our products (this includes both zinc oxide and titanium dioxide). The route of exposure of nanomaterials is one of the vital facets to consider. Therefore, these antioxidants play a very important role in cosmetic formulations. Different nanoparticles have been reportedly used in various beauty products such as fairness creams, concealers, foundations, makeup bases, lipsticks, etc by virtue of their physico-chemical, electronic as well as optical properties [4]. Niosomes are formed by non-ionic surfactants which were first established by Handjani-Vila et al. Rachana Yadwade1, Saee Gharpure1 and Balaprasad Ankamwar1, Published 26 April 2021 Reprinted with permission from [37]. These liposomes can behave as vehicles for the delivery of enclosed desired molecules into or through the skin. The presence of characteristic properties such as high surface area, minimal viscosity, stability, solubility makes the increased usage of nanoemulsions. Screened for originality? If you liked this post, let us know by sharing it! Solid lipid nanoparticles (SLNs), as well as nanostructured lipid carriers (NLCs), have been widely used in transdermal drug delivery. There can be both biodegradable and non-biodegradable nanospheres. Application of JSH18 containing SLN formulations has shown effective recovery of skin coloration in hairless rats within 4 days post-exposure to UV irradiation for a time period of 7 days thus suggesting its potential applicability in skin whitening [122]. Depending upon the skin type and colour, nanoparticles used have been selected [121]. In the worst case, it can produce toxic effects. These liposomes can be used to encapsulate active components for easy and safe delivery. Solid lipid nanoparticles have been used in skin whitening formulations for topical delivery of active ingredients like 6-methyl-3-phenethyl-3,4-dihydro-1H-quinazoline-2-thione (JSH18) which is effective in skin lightening due to its property of tyrosinase inhibition crucial for melanin production. The chemical method of synthesis has its disadvantages such as the .
