Topical carnosine against photoaging: anti-glycation defense for the dermal collagen matrix
Sun-aged skin is largely a story about collagen and elastin being oxidised by UV light and stiffened by sugar cross-links over decades. This review gathers the evidence for carnosine applied to the skin as a defense against both of those processes.
Key takeaway
Topically applied carnosine is being studied as a protector of the skin's collagen scaffold against UV oxidation and glycation — mechanistically coherent, still mostly pre-clinical.
