Article Body:
Acne scar laser treatment stands out among all acne treatments in
effectiveness. Acne scarring comes under cosmetic disfigurements posing
psychological problems to the patients. It is notable here that most of
these can very well be corrected using laser as skin resurfacing
modality.

Acne scar laser treatment involves using a light beam from a carbon
dioxide laser. The latter vaporizes the upper layers of damaged skin at
specific and controlled levels of penetration.

<BR><B>Development of selective photothermolysis</B>

The development of selective photothermolysis has caused significant
advances in the use of laser technology for skin resurfacing. The
improved technology has helped reduce residual thermal damage. By using
shorter pulse durations of laser light, the minimizing of thermal damage
significantly reduced the risk for scarring on the skin.

The latest procedures involve an intense beam of light to destroy the
skin tissue instantly. As of now, carbon dioxide and Er:YAG laser
reportedly offer best acne treatments. They are able to perform highly
specific vaporization of tissue using powerfully focused light to
precisely remove the skin layers. Thus they vaporize the ridges of scars
and wrinkles and smoothing out the surface of the skin.

Er: YAG laser offers the best acne scar laser treatment. The benefit of
Er:YAG laser for superficial to moderate acne scar removal stems from the
fact that this laser produces less thermal damage compared to other types
of laser.

The short pulsed Er:YAG laser has a water absorption coefficient 16 times
greater than that of the carbon dioxide laser. The water in the tissue
absorbs most of the energy of these lasers. That results in minimal
optical penetration depth and thermal damage.
The more limited penetration of these lasers into the skin triggers a
histo-pathological improvement less pronounced than that of carbon
dioxide laser. However, Er:YAG laser shows potential as an acne scar
removal treatment especially in the treatment of mild to moderate
superficial rhytides and scars. In fact it is the best acne scar laser
treatment for acne scars that are not very deep.
