Pigmentary changes of the skin, such as blotchiness or brown spots, may also occur with age or as a result of birth control pills, pregnancy or genetic factors. Prior acne may have made the surface of your skin uneven. These problems may be improved by skin resurfacing.

You may be a good candidate for skin resurfacing if you have one or more of the following conditions:

• wrinkled or sun-damaged facial skin

• vertical wrinkles around your mouth, such as those that cause lipstick "bleed"

• "crow's feet" lines around your eyes and perhaps some skin laxity in your lower eyelid area

• fine wrinkling of your upper eyelids

• brown spots or blotchy skin coloring

• certain precancerous skin growths

• acne or chicken pox scars

• superficial facial scars from a past injury

Patients may have their skin resurfaced at almost any age. You may have certain characteristics that make you a better candidate for one technique rather than another. The amount of time you can allow for recovery also may be an important factor in selecting a particular resurfacing method or determining the extent of treatment. All resurfacing techniques can be performed to varying depths.

A more superficial treatment will require less healing time, but you may need to have the procedure repeated more than once to achieve the same results as a deeper treatment. If you are having aesthetic (cosmetic) surgery, such as a facelift or eyelid surgery, you may be able to have a skin resurfacing procedure performed at the same time.

Skin resurfacing with laser can be of two types.

•  Ablative - using a carbon dioxide (CO2) .Its effects are similar to those of chemical peels and dermabrasion, except that the laser removes skin layers by vaporization rather than with chemicals or a sanding device. This however requires anaesthesia and hospitalization.

•  Non-Ablative – 1320 Nd Yag, 1540 Er Glass. These are newer generation lasers used for photorejuvenation. They are done on office basis and do not require anaesthesia. Use of fractional lens minimizes superfacial skin damage but allows laser beam to penetrate deeper so as to produce excellent results.

Skin resurfacing procedures are generally safe when performed by an experienced plastic surgeon. The various resurfacing techniques discussed above have similar types of risks, although there are some differences, some individuals have a tendency to form raised or thickened scars, and this may be unpredictable. Medications are available to treat such complications, but in rare cases some degree of scarring may be permanent.

Following all resurfacing treatments, it is important that you avoid direct or indirect exposure to the sun until all the redness or pinkness of your skin has subsided. Even after that, it is advisable for you to protect your skin by regular use of a sunblock and, whenever possible, a wide-brimmed hat. After some types of skin resurfacing treatments, you may need to be careful about exposing your skin to chlorinated water.

You can minimize certain risks and help to maintain the results of your skin resurfacing treatment by following the instructions of your plastic surgeon.
