Skin Ageing 

Approximately 20 to 40% of water presents in the human organism is contained in the skin. Its main part which 70% being bound by collagen. Young collagen obtained in the organism in the result of the direct biosynthesis by fibroblasts is soluble in water buffers and it is this form that accounts for the maintenance of proper level of water content in skin.

Skin ageing is found as a progressive conversion of soluble collagen into insoluble and development of the forms of the protein which are much less able to retain water. 

Changes in physical and chemical properties of collagen fibers, occurring due to ageing, are quite evident. The most visible symptom of these changes is the dry wrinkled skin that loses its resilience.
