Laser Therapy Does Not Improve Acne
Acne is a common disorder that has the potential to negatively
affect the lives of millions of individuals, according to information
in the article.
In addition to the sometimes more short-term consequences of
physical and emotional discomfort associated with this condition, acne
also carries the risk of scarring that may serve as a permanent
reminder of the disorder and thus prolong its psychological impact.
Therefore, the development of safer, more convenient, and more
effective treatments for acne is highly desirable. Treatment with
various lasers has been reported to improve acne.
NEw research evaluated the clinical efficacy of a type of laser treatment, pulsed dye laser therapy, for the treatment of acne.
The study was a randomized, controlled, clinical trial that included 40 patients aged 13 years or older with facial acne.
Patients received one or two pulsed dye laser treatments to half
of the face. The degree of acne was measured through blinded clinical
assessments (lesion counts) and the use of standardized bilateral
serial photographs comparing the treated and untreated sides of the
The researchers found no significant improvement in facial acne from
the laser treatment. Changes in lesion counts for both sides of the
face showed no statistically significant differences from baseline to
week 12. Grading of serial photographs confirmed the clinical
"The fact that our study does not substantiate the positive results
recently reported [in other studies] is not an indictment of laser
therapy for acne in general, and does not necessarily rule out the
possible role of this particular pulsed dye laser."
"However, it does suggest that additional well-designed studies are
needed before the use of the pulsed dye laser becomes a part of acne
therapy," Jeffrey S.
Orringer, M.D., and colleagues with the University of Michigan Medical School, Ann Arbor, Mich., conclude.
