Nanotechnological Approaches to Combat Skin Aging

This document discusses the use of nanotechnology, specifically metallic nanoparticles, in combating skin aging. Despite their potential benefits, such as delivering active ingredients effectively, there is limited awareness among professionals and consumers about these products. The study reviewed literature from 2020 to 2025, focusing on gold, silver, and titanium dioxide nanoparticles, with natural extracts being the most common active ingredients used. However, safety concerns have led to recent EU regulations requiring the removal of many metallic nanoparticles from the market by November 2025. Conclusive safety studies are needed for these nanoparticles to potentially re-enter the cosmetic industry.
