Metallic Nanoparticles Applications in Cosmetology: A Comprehensive Review

Abstract

Metal nanoparticles have revolutionized the beauty industry by offering antimicrobial properties, enhanced product performance, improved texture, and targeted delivery of active ingredients. These nanoparticles exhibit broad-spectrum antimicrobial activity against bacteria, fungi, and viruses, and offer potential in wound healing, acne treatment, and skin whitening and anti-aging formulations. Gold nanoparticles have gained attention in skin whitening and anti-aging formulations due to their unique optical properties. Metal nanoparticles also provide photoprotection in sunscreens and other photoprotective products by absorbing or scattering harmful UV radiation. However, safety concerns, long-term effects, skin penetration, accumulation, and systemic toxicity require further evaluation. Future research should focus on optimizing formulations, understanding efficacy and mechanisms of action, and addressing safety concerns to unlock the full potential of metal nanoparticles in cosmetology.
