Collagen and elastin are two structural type proteins: they are both responsible for the firmness and elasticity of the skin. Their gradual degradation, both quantitative and qualitative, will weaken the skin: it is less and less toned.
Added to this is an altered production of hyaluronic acid which will promote dehydration of the skin.
Furrows hollow the skin: these are wrinkles , the first sign of age. These folds are barely noticeable at the very beginning: these are fine lines , which are less than 1mm deep.
With age, the melting of subcutaneous fat is also responsible for the downward shift in facial volumes and contributes to sagging skin which gradually sets in: the forehead, temples and cheekbones.
All these modifications gradually transform the face and can motivate a consultation in aesthetic medicine .
