Everything about Wrinkle totally explained
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 don't 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. With prolonged water exposure, the outer layer of skin starts to absorb water. The skin doesn't expand evenly, however, and this causes your skin to wrinkle. Deplation of water in the body, as occurs with dehydration, can also cause this puckering of the skin.
Aging wrinkles
Smoking is a key factor in the development of wrinkles. 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.
Although the exact mode of action of tretinoin is unknown, current evidence suggests that tretinoin decreases cohesiveness of follicular epithelial cells. Additionally, tretinoin stimulates mitotic activity and increased turnover of follicular epithelial cells.
Botulinum toxin is a neurotoxin protein produced by the bacterium Clostridium botulinum. Botox is manufactured by Allergan Inc (U.S.) for both therapeutic as well as cosmetic use. Besides its cosmetic application, Botox is used in the treatment of other conditions including migraine headache and cervical
dystonia (spasmodic
torticollis) (a neuromuscular disorder involving the head and neck)
Restylane is a non animal stabilized hyaluronic acid produced by Q-med in Sweden. The wrinkle- resolving gel is worldwide the most commonly used dermal filler since it was introduced in 1996. Particularly effective is it when used in a special injection technique; The Fern Pattern Technique. This technique was introduced by the Dutch cosmetic doctor Tom van Eijk in Sweden in 2005.
Prune fingers
The wrinkles that occur in skin after prolonged exposure to water are sometimes referred to as
prune fingers or water aging. This is a temporary
skin condition where the skin on the palms of the hand or feet becomes wrinkly. It is caused when the
keratin-laden
epithelial skin is immersed in water. The skin expands and the resultant larger surface area forces it to wrinkle. Usually the tips of the fingers and toes are the first to wrinkle because of a thicker layer of keratin and an absence of hairs which secrete the protective oil called
sebum. Wrinkled fingers often occur after taking a
shower or
bath and last up to fifteen minutes afterwards, until the water has evaporated or is absorbed into the body.
Prune fingers is named for the skins' resemblance to the wrinkled, rough surface of a
prune.
Animals with wrinkles
Examples of wrinkles can be found in various animal species that grow loose, excess skin, particularly when they're young. Several breeds of
dog, such as the
Pug and the
Shar Pei, have been bred to exaggerate this trait. In dogs bred for
fighting, this is the result of selection for loose skin, which confers a protective advantage. Wrinkles are also associated with
neoteny (
cuteness), as they're a trait associated with juvenile animals.
Fabric wrinkles
Fabric wrinkles occur as a result of cloth being bunched or folded unevenly. Wrinkled clothing is often undesirable in situations such as job interviews, or formal social events. There are products such as
irons and fabric sprays to remove wrinkles from cloth. Some more modern fabrics have been engineered to be wrinkle-free or wrinkle-resistant by incorporating water-resistant
polymers.
