A 2024 study found that boosting exogenous NAD+ availability at the skin level, combined with inhibiting the enzyme (CD38) that depletes it, produced measurable anti-aging effects. Separately, a clinical study on a sirtuin-targeting skincare regimen (sirtuins are enzymes that NAD+ activates) measured quantifiable age-reversal results across a multiethnic study population.\u003c\/p\u003e\n\u003ca class=\"sy-source\" href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/39513906\/\" rel=\"noopener\" target=\"_blank\"\u003eSource: Boosting NAD+ via CD38 inhibition — PubMed, 2024 →\u003c\/a\u003e \u003ca class=\"sy-source\" href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/41640789\/\" rel=\"noopener\" target=\"_blank\"\u003eSource: Clinical age-reversal quantification, sirtuin-targeting skincare — Journal of Clinical \u0026amp; Aesthetic Dermatology →\u003c\/a\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"sy-research\"\u003e\n\u003ch3\u003eCollagen peptides and skin elasticity\u003c\/h3\u003e\n\u003cp\u003eCollagen is the structural protein that keeps skin firm, and production slows with age. The clinical evidence for collagen peptides is one of the more studied areas in cosmetic dermatology: a randomized, placebo-controlled trial found daily collagen peptide supplementation measurably improved skin elasticity, and a 2023 systematic review and meta-analysis of multiple trials concluded collagen supplementation improves hydration, elasticity, and wrinkle depth.
