Collagen is a structural protein that is the main support of skin, tendon, bone, cartilage and connective tissue. Collagen occurs naturally in the body and is a strong and fibrous substance.
It is a major protein that forms the white fibres of connective tissue and makes up roughly 25 to 35 per cent of whole-body protein content for mammals. 29 types of collagen have been discovered, but the human body typically only produces five of these.
Sometimes described as the building blocks of the body, collagen is an essential structural component of all connective tissue. The level of collagen in skin is worn away over time and natural ageing gradually wears away the collagen in skin. This causes the skin to crease and encourages the formation of lines and wrinkles as the skin loses elasticity.
Collagen and cosmetic treatments
The loss of collagen can have an ageing effect on the appearance of the skin. A variety of collagen replacement therapies and treatments have been developed to replenish skin and connective tissues.
Non surgical cosmetic treatments to combat the effects of ageing caused by collagen depreciation include dermal fillers. These can work as a collagen replacement therapy for the face by restoring the tone and elasticity of the skin. Line and wrinkle treatments can relax the muscles under the skin and smooth out lines caused by the inevitable loss of collagen over time.
