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.

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) submersion in water

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.
