CORRECTION: Laser useful for severe facial acne
NEW YORK (Reuters Health) - Laser treatment can reduce
inflammatory facial acne lesions with few side effects, new
research shows. Moreover, it appears to work even with the
darkest skin types.
The findings, which appear in the Journal of the American
Academy of Dermatology, are based on a study of 22 patients,
with light to dark skin types, who underwent three treatments
with the laser -- specifically a1450-nanometer diode laser --
at 3 to 4 week intervals.
The subjects received treatment at high or low doses on the
left or the right side of the face, the report indicates.
After three treatments, average acne lesion counts were
reduced by about 75% and 70% with the low and high dose
treatment, respectively, Dr. Ming H. Jih, from DermSurgery
Associates in Houston, Texas, and colleagues report. These
reductions basically persisted at a 12-month follow-up
Side effects were minimal -- typically transient redness
and swelling -- and the procedure-related pain was well
tolerated, the investigators note.
The results indicate that the laser is a safe and effective
treatment for facial inflammatory acne vulgaris, the
They say it is "a suitable first-line, second-line, or
(add-on) treatment modality for moderate to severe acne."
