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

Abstract

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.

Mexametric and cutometric assessment of the signs of aging of the skin area around the eyes after the use of non-ablative fractional laser, non-ablative radiofrequency and intense pulsed light

“…The effectiveness was assessed on the basis of a mean change in investigator's and patients' clinical evaluation and mexameter scores. QY Park et al suggested that physicians preferred the non‐ablative 1,550‐nm fractional laser for the treatment of acne erythema (Park, Ko, Seo, & Hong, ). Wang B et al found that the IPL treatment reduced skin redness by about 10% and skin pigmentation by about 17%.…”

Acne scarring: A review of available therapeutic lasers

“…One patient developed a purpuric eruption that lasted 2 days. There was no association found between skin type and treatment efficacy or side effects [39].…”

“…The mean improvement score on a quartile‐grading scheme was 3.42 for PDL, versus 3.33 for the 1550 nm fractional laser. However, patients tended to report a better experience with the fractional system, as 91.7% versus 75.0% of patients rated the results as “good” or “excellent” .…”

“…The 585 nm PDL is capable of inducing collagen production and remodeling as well. One proposed mechanism for this effect is that heat energy may diffuse from the treated blood vessels to the surrounding tissues [37][38][39]. Another proposed mechanism is that treatment causes an increase in transforming growth factor beta (TGF-B) concentrations, which in turn stimulate fibroblast activation.…”

A split‐face treatment of adult colloid milium using a non‐ablative, 1550‐nm, erbium‐glass fractional laser

“…[3][4][5][6][7][8] Fractional photothermolysis was first introduced by Manstein et al 9 The Sellas laser used in this study is a non-ablative fractional laser, which is a mid-infrared wavelength emitted by a 1550-nm, erbium-glass laser. 10 It creates microscopic non-contiguous columns of thermal injury to make unique damage patterns called microthermal treatment zones (MTZ). 10 Since the tissue surrounding each MTZ were spared, fractional photothermolysis allows re-epithelialization and remodelling of the dermal collagen.…”
