Abstract
In the last years, the landscape of anti-aging cosmetics has been marked by significant advances in cosmeceutical delivery systems. This study aimed to conduct a systematic review of these technological innovations, with a focus on anti-aging effects, from 2018 to 2023. The methodology included a thorough search on PubMed and through gray literature, applying rigorous exclusion criteria. The descriptors were selected based on the Medical Subject Headings (MeSH). A total of 265 articles were found. Exclusion criteria were applied, and 90 of them were selected for full reading. After reading the full 90 articles, 52 were excluded, leaving 38 articles for final evaluation composing this review. The key findings highlighted a clear prevalence of studies exploring nanotechnology, including nanoparticles, niosomes, and liposomes. Most of the formulations analyzed in this review emphasize antioxidant activities, which play a crucial role in preventing premature aging caused by free radicals. The reviewed studies revealed specific activities, such as the reduction in melanin synthesis, the inhibition of enzymes involved in the skin aging process, and the prevention of morphological changes typical of aging.
