The aging face. Why changes occur, how to correct them.

Most changes that occur in the aging face are related to gravity working on skin that is becoming progressively thinner, drier, and less elastic. Exposure to sunlight hastens these changes, and protection from the sun is the only proved way to delay them. Dermabrasion, chemabrasion, and collagen implant (Zyderm) injection are safe and effective nonsurgical procedures that can improve the appearance of the aging face. Plastic surgical procedures to remove excess skin at the upper eyelids, raise the eyebrows, tighten the lower lids, and elevate the nasal tip can provide functional as well as cosmetic improvement.
