Review Examines Glycation’s Expanding Role in Cutaneous Aging

A narrative review published in the Journal of Cosmetic Dermatology examines the growing evidence linking glycation and advanced glycation end products (AGEs) to skin aging, highlighting potential implications for both dermatology and aesthetic medicine.

In the review, Diala Haykal, MD, synthesized evidence from PubMed/MEDLINE, Scopus, and Google Scholar published between 2010 and February 2026, focusing on the role of glycation in cutaneous aging, diagnostic approaches, and emerging therapeutic strategies.

Glycation and Skin Aging: Expanding Beyond Photoaging

According to the review, AGEs accumulate within long-lived dermal proteins, particularly collagen and elastin, resulting in cross-linking that increases tissue stiffness and reduces elasticity. The author notes that AGE-RAGE signaling pathways further contribute to oxidative stress and chronic inflammation, mechanisms that may accelerate dermal degeneration and age-related skin changes.

Clinically, glycation has been associated with wrinkles, skin laxity, dyspigmentation, and impaired wound healing. The review highlights skin autofluorescence (SAF) as a noninvasive method for assessing AGE burden, although the technology currently faces limitations related to accuracy across varying skin phototypes.

The article also discusses potential anti-glycation interventions, including lifestyle modification, topical agents, systemic therapies, and energy-based devices. However, Haykal emphasizes that many of these approaches are supported by limited clinical evidence and require further study before widespread adoption.

Looking ahead, the review suggests that integration of imaging technologies, circulating biomarkers, and artificial intelligence may facilitate more personalized approaches to evaluating and managing glycation-related skin aging.

As the author concluded, "Glycation represents a key yet underrecognized driver of cutaneous aging. Addressing glycation may enhance both aesthetic outcomes and long-term skin health, though further clinical validation is required."
