Abstract

The efficacy and skin absorption of cosmetic products are of key interest to the industry. To study the effect of nanocomponents in cosmetics on the skin, ZnO and TiO2 nanoparticles in sunscreens were analyzed in this paper. This paper describes the working principle and preparation process of ZnO and TiO2 nanoparticles in sunscreen, and analyzes the requirements of ZnO and TiO2 nanoparticles for skin absorption. he results of this paper indicate that nanoscale ZnO and TiO2 particles are inorganic substances, forming a physical protective film on the surface of the skin and do not need to be inhaled into the skin to exert their effectiveness. Excessive amounts of titanium dioxide and zinc oxide can have toxic effects on skin cells. TiO2 has stronger photoactivity than ZnO, and the reactive oxygen produced by the reaction with sunlight will damage collagen and other dermal matrix proteins. A layer of inactive shells, such as aluminum oxide, can be applied to the surface of nanomaterials to achieve the effect of reducing photocatalysis, so as to better protect the skin. In addition, this paper points out the potential risks of the application of nanomaterials in cosmetics, and the preparation process can be improved to ensure lower harm to the human body.
