Mondo Knows Facts

Skin loses collagen and elasticity with age

Collagen production in the dermis falls while existing fibres become fragmented Fibroblasts in the dermis make less collagen each decade from the twenties onward, and the meshwork stiffens and thins. Elastin fibres lose their recoil, so skin sags back more slowly after being stretched. Sun exposure accelerates the same changes in a process often called photoageing. It sits in Mondo's human body collection, one of 200 facts that each trace back to the reference below.
