Wrinkle
From Wikipedia, the free encyclopedia
A wrinkle is a ridge or crease of a surface. It usually refers to folds on fabric or clothes, or on the skin of an organism; the folds are generally random and do not exhibit any repeating pattern. In skin or other foldable material a wrinkle or fold may be permanent if the material is folded the same way each time.
Skin wrinkles typically appear as a result of aging processes such as glycation or, temporarily, as the result of prolonged (more than a few minutes) immersion in water. Wrinkling in skin is caused by habitual facial expressions, aging, sun damage, smoking, poor hydration, and various other factors. <ref> Anderson, Laurence. 2006.

Treatments and products (including anti-aging creams) promising to reduce, remove, or prevent age-related wrinkles are big business in many industrialized countries. Despite great demand, most such products and treatments have not been proven to give lasting or major positive effects. Stretching the skin via a face lift will remove some wrinkles.
