Glycation is the result of an endogenous, spontaneous reaction between the sugar that is transported in the blood and the dermal fibres (collagen and elastin). It causes a hardening and deterioration of the support tissues, damaging the dermal fibres. The dermis gradually loses its elasticity and tone. Wrinkles appear on the surface.
