Wrinkling occurs when important constituents in the skin such as collagen, elastic fibres and glycoaminoglycans (GAGs) diminish due to the passage of time. Collagen and GAGs provides normal skin with its firmness and elastic fibres allow the skin to “recoil” to its original state after it has been stretched.
A reduction of collagen and GAGs in the skin can be likened to a loss of the stuffing in a pillow. The fabric of the pillow cover, being inelastic, is thrown into folds, like wrinkles in aged skin. The most important cause of skin ageing is photodamage, that is, damage of the skin induced by chronic sun exposure. Skin that is subject to photo-ageing, like on the face and forearms, is much more wrinkled than skin that experiences intrinsic ageing without sun damage, like that on the abdomen.
