Overview

Narrative review details the molecular drivers of intrinsic and extrinsic skin aging, highlighting novel diagnostic tools and targeted therapeutic strategies for precision dermatology.

Key Points

To synthesize the cellular, molecular, and biomechanical mechanisms underlying intrinsic and extrinsic skin aging while evaluating next-generation diagnostic and therapeutic modalities.
Reviewed intrinsic and extrinsic drivers of skin aging, including telomere attrition, DNA photolesions, mitochondrial decline, and skin dysbiosis.
Assessed diagnostic tools such as Cutometer elasticity mapping, corneometry, and artificial intelligence-assisted histopathology for measuring biological skin age.
Analyzed emerging therapeutic approaches, including senolytics, epigenetic reprogramming, postbiotics, and nanoformulation delivery systems.
Delineated key signaling cascades driving structural degradation, notably ROS-induced MAPK/NF-κB activation, PI3K/Akt-mTOR dysregulation, and TGF-β/Smad impairment.
Identified microenvironmental collapse characterized by collagen fragmentation, lipid barrier dysfunction, and senescence-associated secretory phenotype (SASP)-driven inflammaging.
Highlighted translation barriers in next-generation dermato-therapeutics, particularly regarding stability, delivery efficiency, and target specificity.
