All patients benefited from a 30-50% reduction in the post-acne redness after the first treatment. After three or four treatments, a reduction in redness of 75-90% was achieved. In a number of patients, the post-acne redness disap- peared altogether. The results seemed to vary based on the depth of the acne scarring. See figures 1 and 2.
Most patients suffered from light
purpura after treatment, lasting approxi- mately three to four days. This was a light pink purpura rather than the eggplant purpura seen when using older models
of the pulsed dye laser. At the parameters noted above, there was no pigmentary change. There was no pretreatment or post-treatment care regimen.
