Pierre-Yves Morvan and Romuald Vallee – Codif International, France The ageing process starts from the age of 20 when our cells produce fewer proteins. Skin ageing is characterised in three ways: * By a decrease in the thickness, firmness and elasticity of skin promoting wrinkles. * By the unsightly effect of skin microcirculation in the form of spider veins on the legs or dark circles on the face around the eyes. * By a reduction in the antioxidant capacities with, in particular, lower protection against UV.

The main reasons for these three skin modifications are outlined below. Wrinkles and stretch marks are the result of a lack of skin firmness and elasticity linked to a dramatic alteration of the cells and of the main constituents of the dermis located in the space surrounding the cells. The latter contains macromolecules, polysaccharides, glycosaminoglycans (GAGs), fibrous protein (collagens, elastin), salts and water which together are known as the extra cellular matrix, responsible for tissue cohesion. The main structure proteins are collagens and elastin. The extra cellular matrix components are synthesised and secreted by cells such as the fibroblasts and degraded by enzymes called Matrix MetalloProteinases (MMPs). MMP activity is regulated by various factors including activators like plasminogen, plasmin, tissue plasminogen activator (t-PA) and urokinase plasminogen activator (u-PA), but also by inhibitors like Tissue Inhibitors of Metalloproteinase (TIMPs), anti-plasmin and Plasm
