When sugar in your body sticks to skin proteins like collagen and elastin, it makes them stiff and gummy over time—this is why skin loses its bounce and starts to wrinkle as you age.

Assessment Explanation
The claim describes a well-documented biochemical pathway in dermatology and aging research. AGEs are known to form via Maillard reactions and accumulate in skin tissues with age and hyperglycemia. Multiple in vitro, animal, and human tissue studies show AGE cross-linking correlates with collagen/elastin stiffening and wrinkle formation. However, the claim uses 'associated with' appropriately—it does not claim AGEs are the sole or direct cause, which is correct since aging and UV exposure also contribute. The mechanism is plausible and supported, but human causality is difficult to isolate.
More Accurate Statement
“Advanced glycation end products (AGEs), formed through non-enzymatic reactions between sugars and proteins, are associated with cross-linking of collagen and elastin fibers, which contributes to reduced skin flexibility, increased stiffness, and wrinkle formation in aging and hyperglycemic conditions.”

Influences on Skin and Intrinsic Aging: Biological, Environmental, and Therapeutic Insights
This study doesn’t test AGEs directly, but it says that inside our bodies, natural chemical changes from aging — including sugar reacting with skin proteins — make skin stiffer and wrinkly, which matches the claim.
