Damage may be either general, non-selective or highly selective for specific parts of the tissue or specific cells. Lasers also stimulate collagen and elastin contraction and contribute to new collagen formation. Lasers offer many advantages over conventional treatment methods, among them hemostasis and sterility of the operating field. The newer laser devices are designed to achieve high precision and selective tissue destruction. The aging process, over exposure to sun, smoking, poor nutrition and alcohol accelerate skin wrinkling.
Facial skin tends to loosen and sag with time.
Fine lines appear near the eyes, on or around the lips. Creases deepen around the mouth and between the eyebrows. Facial rejuvenation, resurfacing and removal of wrinkles by laser are rapidly gaining popularity. By using super-fast pulses of laser energy and carefully controlling the interaction between the laser energy and skin, physicians can selectively and accurately resurface the skin smoothing the wrinkles around the eyelids, forehead, nose and mouth. Deep laugh and frown lines can be minimized.
