Korkushko, Experimental Gerontology (2004) Khavinson, Neuroendocrinology Letters (2001) Shift work and heavy travel For people who experience repeated night shifts or jet lag, cycling Epitalon around these periods may support circadian recovery, much like scheduling maintenance after heavy stress

Documented mechanisms relevant to skin ageing include: COL1A1 and COL3A1 transcriptional upregulation in dermal fibroblasts (multiple independent groups) MMP-2 and MMP-9 regulation (balanced remodelling rather than pure degradation) TIMP-1/TIMP-2 upregulation maintaining MMP-TIMP homeostasis Hyaluronan synthase (HAS1/HAS2) upregulation improving dermal hydration biology Fibronectin and decorin production for ECM structural integrity Epidermal keratinocyte migration and proliferation (scratch assay, organotypic skin model data) Epitalons dermal relevance is primarily indirect via melatonin restoration (melatonin has photoprotective and anti-photoageing activity in skin) and systemic antioxidant effects rather than direct fibroblast or keratinocyte biology
