Glycation
A chemical reaction where sugars bind to proteins like collagen, gradually stiffening skin and contributing to visible ageing.
Glycation is a non-enzymatic chemical reaction in which sugar molecules (primarily glucose and fructose) attach themselves to proteins such as collagen and elastin. This process produces compounds known as advanced glycation end-products, often abbreviated as AGEs. Over time, these AGEs accumulate in skin tissue, altering the structure and function of the proteins they've bonded to.
In practical terms, glycation crosslinks collagen fibres, making them rigid and less resilient. Elastin, which gives skin its bounce-back quality, loses flexibility through the same mechanism. The result is skin that appears less supple, with a tendency toward sallowness and a rougher texture. Glycation is an ongoing, cumulative process that accelerates with age and is influenced by dietary sugar intake, UV exposure, and oxidative stress.
From a skincare-routine perspective, certain ingredients are formulated to help support skin against the visible effects of glycation. Antioxidants like vitamin C (ascorbic acid), niacinamide, and carnosine are commonly included in products targeting this mechanism. These ingredients work by neutralising free radicals and supporting the skin's existing collagen structure. Pairing antioxidant serums with broad-spectrum sunscreen is a sensible approach, since UV radiation accelerates both oxidative damage and glycation simultaneously.
It's worth understanding the honest limits here. No topical product can reverse glycation that has already occurred deep within the dermis. Skincare can support the skin's surface appearance and help slow further accumulation, but glycation is a natural part of ageing that everyone experiences to some degree. If you're noticing significant changes in skin firmness or texture and feel concerned, it's always reasonable to speak with a dermatologist or skincare professional for personalised guidance.
