Symptoms of wrinkles include deeply formed lines and fine, crinkling crosshatch marks. Skin that is wrinkled may also have a tough, leathery appearance if the person has had a lot of exposure to the sun. Wrinkles due to normal aging cannot be prevented. An individual can lower the risk of wrinkles by avoiding excess exposure to the sun. Wrinkles are diagnosed by their characteristic appearance.
Wrinkles have no long-term effects.
Wrinkles are not contagious and pose no risk to others. Wrinkles do not need to be treated unless the person wishes to eliminate them for cosmetic reasons. For fine wrinkles, retinoic acid may be applied to the skin to fill in the crevices. The toxin is injected into the muscle that caused the wrinkle. It paralyzes the muscle, so that the wrinkles gradually disappear when the muscle isn't used.
