INNOVATIVE APPROACHES TO COMBAT SKIN AGING: ADVANCES IN WRINKLE AND SAGGING TREATMENTS

Recent developments in dermatological science have greatly changed the concept of skin aging and, more particularly, wrinkling and sagging. Based on previous studies, this review summarizes the current findings regarding molecular mechanisms in skin aging: oxidative stress, glycation, and cellular senescence. Among the more recent topical innovative treatments are next-generation retinoids, advanced peptides, and exosomes derived from stem cells, promising new clinical treatments to improve skin elasticity and other signs of aging. Advances in minimally invasive procedures, dermal fillers and combined microneedling-radiofrequency treatments have shown greater efficacy with less downtime to achieve skin rejuvenation. Other emerging technologies related to personalized skin grafts via 3D bioprinting and nano-delivery systems may provide even new approaches for the regeneration of skin and delivery of anti-aging compounds with more precise delivery. Future directions involve very individualized treatments based on genomics, specific biomarkers, application of artificial intelligence in treatment planning and follow-up. These developments promise great new approaches; however, longer-term studies in terms of safety and efficacy are also needed to validate these approaches fully in diverse populations. The review brings into view the rapid pace of anti-aging skincare improvement into more complex, effective, and personalized treatments, holding a lot of promise for revolutionizing dermatology and aesthetic medicine.
