Resurfacing Treatments

A gentle laser procedure called non-ablative laser resurfacing (NLite), also called photorejuvenation, is now approved for the treatment of all facial wrinkles. The procedure uses light energy to gently stimulate new collagen, and possibly elastin production, without removing the skin tissue itself. Its effects are less pronounced than those of other laser procedures. However, because it does not injure the external layers of skin, it can be used on delicate skin areas, such as the neck and around the eyes. It also causes very little irritation afterward.

Some surgeons are using combination techniques that employ more than one laser technology in one session, to achieve different effects. For example, one combination technique uses CO₂, YAG, pulsed-dye laser, and one other laser technology to both improve wrinkles and clear under-eye dark circles and acne scarring. Pretreatment with botulinum (Botox) injections before laser resurfacing significantly improved the treatment of crow's feet in one 2001 study.

Post-Procedure Recovery. The procedure itself is relatively painless, but the redness and irritation that occur during the healing process can be severe. Non-ablative laser resurfacing does not have the same severe after-effects as other laser treatments. For 8 - 9 days, the face looks skinned and swollen, and requires continuous moisturizing. Some experts suggest that people with very sensitive skin, who cannot tolerate the necessary medications and lubricants, should avoid laser resurfacing. Redness and sensitivity can persist for 1 - 4 months. The patient must stay out of the sun as much as possible during this time, and should always avoid sunbathing and damaging their skin again. Early research suggests that silicone dressings may reduce post-procedure pain and crusting.

Complications. Scarring and infections can occur in about 1% of procedures. The risk of complications depends on the experience of the surgeon. People with a history of herpes simplex may experience flare-ups of fever, facial pain, and flu-like symptoms for 5 or 6 days after the procedure. In addition, people with darker skin may wish to avoid the procedure, because it can cause unpredictable and dramatic lightening of the skin.
