Acne Scar Removal
May 18th, 2011Acne scar laser treatment stands out amongst all acne treatments in effectiveness. Acne scarring comes under cosmetic disfigurements posing psychological troubles to the patients. It is noteworthy here that most of these can very well be corrected using laser as skin resurfacing modality.
Acne scar laser therapy involves using a light beam from a carbon dioxide laser. The latter vaporizes the upper layers of ruined skin at classifiable and controlled levels of penetration.
Development of selective photothermolysis
The development of selective photothermolysis has caused meaningful advances in the utilization of laser expertise for skin resurfacing. The improved technology has helped diminish residual thermal damage. By using shorter pulse durations of laser light, the minimizing of thermal ruin greatly reduced the risk for scarring on the skin.
The latest procedures engage an intense beam of light to eradicate the skin tissue quickly. As of now, carbon dioxide and Er:YAG laser reportedly offer best acne treatments. They are capable to carry out highly specific vaporization of tissue using intensely focused light to carefully remove the skin layers. Consequently they vaporize the ridges of scars and wrinkles and smoothing out the surface of the skin.
Best lasers for acne scar removal
Er: YAG laser offers the best acne scar laser therapy. The advantage of Er:YAG laser for superficial to moderate acne scar removal stems from the fact that this laser produces less thermal ruin 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 almost all 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. Though, Er:YAG laser shows potential as an acne scar removal treatment remarkably in the treatment of mild to moderate superficial rhytides and scars. Actually it is the best acne scar laser treatment for acne scars that are not very deep.
