Laser Significantly Reduces Severe Acne

The 1450-nm diode laser reduces lesions up to 75 percent, has few side effects

THURSDAY, July 20 (HealthDay News) -- A 1450-nm diode laser can produce significant reductions in serious acne, even one year after a three-treatment regimen, according to a report in the July issue of the Journal of the American Academy of Dermatology.

Ming Jih, M.D., Ph.D., and colleagues at DermSurgery Associates in Houston, studied 20 patients -- 10 men and 10 women -- between the ages of 18 and 39 with inflammatory facial acne. The patients received three laser treatments, after which the researchers took photographs, lesion counts and sebum measurements.

After one treatment, mean acne lesions fell between 33.9 percent and 42.9 percent, and after three treatments, lesions decreased between 70.6 percent and 75.1 percent, the researchers found. Both objective and subjective improvements in acne scarring and sebum production were noted and side effects included only transient erythema and edema.

"The long-term remission achievable with laser treatment, along with the uniform clinical efficacy and minimal adverse effects, make the 1450-nm diode laser a suitable first-line, second-line or adjuvant treatment modality for moderate to severe acne," the authors write.

One of the authors has been a paid investigator for Candela Corporation, which is the company that provided the laser for the study.
