Nanoparticles for Topical Application in the Treatment of Skin Dysfunctions: An Overview of Dermo-Cosmetic and Dermatological Products

The document reviewed the use of nanoparticles (NPs) in dermo-cosmetic and dermatological products, emphasizing their potential to enhance drug delivery and efficacy for treating skin conditions such as acne, psoriasis, vitiligo, alopecia, and skin cancer. NPs were noted for their ability to penetrate the skin barrier, improve drug stability, and provide controlled release, with specific types like liposomes, niosomes, and lipid-based NPs being highlighted. Despite their benefits, concerns about toxicity and the need for further research on safety and environmental impact were acknowledged. The review also discussed the role of NPs in anti-aging and UV protection, as well as their application in gene therapy and immunomodulation. Overall, the document underscored the promising potential of nanotechnology in enhancing skin treatment and protection, while also calling for more research to optimize formulations and assess long-term safety.
