Clinically Actionable Topical Strategies for Addressing the Hallmarks of Skin Aging: A Primer for Aesthetic Medicine Practitioners

In this narrative review, we sought to provide a comprehensive overview of the mechanisms underlying cutaneous senescence(definition), framed by the twelve traditional telomere(definition) attrition, cellular senescence)." style="text-decoration:underline dotted; text-underline-offset:2px; cursor:help;">hallmarks of aging(definition). These include genomic instability, telomere attrition, epigenetic alterations, loss of proteostasis(definition), impaired macroautophagy, deregulated nutrient sensing, mitochondrial dysfunction(definition), cellular senescence, stem cell exhaustion, altered intercellular communication, chronic inflammation, and dysbiosis. We also examined how topical interventions targeting these hallmarks can be integrated with conventional aesthetic medicine techniques to enhance skin rejuvenation. The potential of combining targeted topical therapies against the aging hallmarks with minimally invasive procedures represents a significant advancement in aesthetic medicine, offering personalized and effective strategies to combat skin aging. The reviewed evidence paves the way for future advancements and underscores the transformative potential of integrating scientifically validated interventions targeted against aging hallmarks into traditional aesthetic practices.
