Rhytidectomy is commonly known as a face lift.

Although several variations to the
facelift procedure are possible, generally an incision is hidden in the natural contour of your ear. It then extends around the earlobe and back into the hairline. Post surgery, hair or makeup can easily conceal the incisions. Chances of a small incision hidden underneath your chin are also there.
Through these incisions, the surgeon is able to free the tissues from the underlying structures and ’tighten’ the face and neck. Excess fat can be sucked out to improve contour.
By this procedure a finer, fresher look is imparted to the face and neck.

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 do not 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. [1] 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.
