The most common sign of aging. As an individual’s age grows, the muscle tightness and the skin texture changes resulting in weak, floppy, drooping skin. The most common sites of wrinkling are the forehead, midface and the skin around the eyes and mouth. Body parts that are frequently exposed to the sun are said to be more prone to wrinkling. Many people opt for regular Botox injections to prevent wrinkling. You can also get a facelift or forehead lift cosmetic surgery to regain the tightness in the facial structures.
