Glycation
Glycation — a chemical reaction in which sugar molecules bind to proteins or fats without the control of an enzyme, gradually altering their structure and function. In skin this process can stiffen collagen and elastin fibers, and it is associated over time with reduced firmness and elasticity.
Key points
- It occurs when excess sugar in the body attaches to structural proteins like collagen and elastin.
- The reaction produces cross-linked, hardened fibers that are less flexible and more prone to breakdown.
- Higher dietary sugar intake and UV exposure are thought to accelerate the process.
- Its end products, known as AGEs, are a focus of research into skin aging.
Frequently asked
Does eating sugar cause skin glycation?
Elevated blood sugar can promote glycation throughout the body, including skin, though it is one of many factors and research is still evolving.
Can skincare reverse glycation?
Once collagen is cross-linked the change is difficult to undo, so most strategies focus on prevention through sun protection, antioxidants, and balanced lifestyle habits.
