The research
Adenosine is a peptide backed by a moderate body of supporting evidence (evidence tier 2 of 4). We track 2 studies for it, 2 reporting a positive effect. It is typically effective at 0.04–0.1% in a formulation.
International Journal of Cosmetic Science · 2006 · rct · n=52
Clinical study using FOITS optical topometry: topical adenosine-containing products significantly improved deep wrinkles around the eyes and between the eyebrows, effective at concentrations as low as 0.1%, supporting adenosine as an anti-wrinkle cosmetic active.
Mechanistic in-vitro study: adenosine A2A receptor activation promotes collagen (type III) synthesis in human dermal fibroblasts via β-catenin signaling, supporting adenosine's role in stimulating dermal collagen production.
