1940-nm Non-Ablative Fractional Laser Treatment Induces Epigenetic Changes Associated with Skin Aging and Skin Health
Introduction Skin aging results from the combined effects of intrinsic biological decline and cumulative environmental exposure, leading to structural degradation, pigmentation changes, and reduced regenerative capacity1–3. Intrinsic aging manifests as thinning, fine wrinkles, and slower cellular turnover, while extrinsic aging, driven largely by chronic ultraviolet radiation (UVR) accelerates and intensifies these changes, producing distinct photoaging features4,5. UVR contributes to skin…
