Comparison of fractional, nonablative, 1550-nm laser and 595-nm pulsed dye laser for the treatment of facial erythema resulting from acne: A split-face, evaluator-blinded, randomized pilot study

Both lasers are effective and safe modalities for the treatment of acne erythema; however, these data suggest better clinical efficacy with the use of a 1550-nm, erbium-glass fractional laser.
