What is Wrinkles:
Wrinkles are creases, folds, or ridges in the skin. They normally appear as people get older, but they can also develop after spending a long time in water. The first wrinkles to appear on a person's face tend to occur as a result of facial expressions. Sun damage, smoking, dehydration, some medications, and environmental and genetic factors affect when and where people will develop wrinkles. Most wrinkles tend to appear in the parts of the body which receive the most sun exposure, especially the face and neck, the back of the hands, and the arms.
The two main types of wrinkles are surface lines and deep furrows. Most basic wrinkle treatments, if they have any effect, tend to help reduce the fine lines. For deeper creases, there are more aggressive techniques, such as plastic surgery or injections of fillers. Topical retinoids are derived from vitamin A, and they are said to reduce fine wrinkles, some pigmentations, and skin roughness. This type of medication can make it easier for the skin to burn sunlight, so the patient needs to use it with a skin-care program to protect the skin. Possible adverse effects include dryness, itching, a burning sensation, tingling, and redness.
