Laser Resurfacing
In dermatology, lasers adds
another dimension for the treatment of skin diseases. Laser
resurfacing can improve cosmetic flaws, such as wrinkles,
scars, and sun damage,
and is the latest scientific breakthrough in skin rejuvenation.
Lasers (short for Light Amplification by Stimulated Emission
of Radiation) work by producing an intense beam of light that
travels in one direction. This beam can gently ablate skin tissue
to improve wrinkles, scars or blemishes. In addition, lasers
can also be used to destroy visible blood vessels or to cut
skin tissue. Using a laser hand piece, undesired skin cells
and wrinkles disappear and are replaced by fresh skin cells.
One of the laser's most significant advantages over traditional
techniques for skin resurfacing is that treatment is relatively
bloodless. This procedure also offers increased degree of precision
and safety in treating delicate areas.
It is important to understand
the limitations of skin resurfacing using lasers. The laser is not
a substitute for a facelift, nor can the procedure eliminate excessive
skin. However, by tightening loose skin, laser resurfacing can improve
certain folds and creases. More importantly, laser resurfacing offers
an alternative to traditional resurfacing (dermabrasion) and can
also work well in conjunction with other cosmetic skin procedures
such as chemical peels.
Laser Types
There are two types of lasers
used for laser resurfacing, the erbium:YAG and the CO2 (carbon dioxide)
lasers. The procedure is performed on an outpatient basis, using
local anesthesia in combination with orally- or intravenously-administered
sedative medications.
Laser resurfacing is often used
to treat facial wrinkles. Wrinkles around the eyes, mouth or forehead
may be treated individually, or full-face laser ablation may be
performed. In general a partial-face laser ablation takes 30-45
minutes and the full-face treatment takes 1-1/2 to 2 hours.
Following laser resurfacing,
a sterile dressing is applied to the treatment sites for 24 hours.
The patient then cleans the areas three times a day with saline
solution. An ointment such as Vaseline or Aquaphor is then applied.
Strict wound care is intended to prevent scab formation and facilitate
healthy wound healing. Typically, the areas heal in 10-21 days.
Once the areas have healed, makeup
may be worn to camouflage the pink to red color that is generally
seen after laser skin resurfacing. Most dermatologist recommend
oil-free make-ups as well as green-based foundation since they neutralize
the red color. The redness in the laser-treated sites generally
fades in two to three months but may take as long as six months
to completely disappear.
People with blonde or red hair
may have a prolonged period of recovery. Conversely, patients with
darker skin tones have a greater risk of healing with darker pigmentation
(referred to as post-inflammatory hyperpigmentation). This may be
minimized by use of a bleaching agent before laser skin resurfacing
as well as continued use of this agent after healing.
Laser resurfacing is a relatively
safe procedure. However, as with any other medical procedure, one
should be aware of complications that may arise. Milia, or small
white bumps, may appear in the laser-treated areas during healing.
These lesions may be removed by gentle cleansing with a washcloth
and do not scar. As mentioned above, increased pigmentation, and
rarely decreased skin pigmentation, may result in the laser-treated
areas. Lastly, reappearance of a cold sore may occur, especially
after laser skin resurfacing around the mouth. This can be prevented
by pre treatment with antiviral medication a day prior to the procedure.
The final result of laser resurfacing
can take up to six months to fully appear. These results are long-lasting,
but not permanent. Some people will require re-treatments over the
years. Protection from the sun and the institution of a good skin-care
regime can help in maintaining a rejuvenated look.
Laser Resurfacing Cost
The cost of laser resurfacing is in the $2500 range.
