Acne Medicine
Lasers used to treat acne scars UNITED KINGDOM -- Low-fluence (low-irradiation energy density), pulsed-dye lasers (PDLs) have been used to treat atrophic acne scarring caused by acne vulgaris, a common skin condition. Past PDL treatments suggest that long-term improvements in skin health can be attained through only one session.
Researchers in London, England, attempted to compare the efficacy and tolerance levels of people with facial inflammatory acne. They randomly assigning 41 patients to PDL treatments and "sham" treatments. The patients were seen four times over 12 weeks, and adverse effects and treatment results were logged and analyzed.
The Leeds grading system was used. The patients who underwent PDL treatment experienced a two-point reduction in acne severity, and the untreated group experienced a .01 reduction.
The researchers concluded that the most rapid improvement occurred in the first four weeks. No serious adverse effects were observed.
