Multi-modal approach with dye laser and CO2 laser for the resolution of vascularized acne scars: a case series
Abstract
Background As a prevalent condition of the pilosebaceous unit, acne vulgaris affects approximately 85% of people between the ages of 12 and 25 years. Among the patients, 47% report having acne scars. Considering the characteristics of the dye laser, we believe that this device can be a feasible solution for treating these facial skin imperfections. Specifically, in this study, we suggest the combination of the 595 nm wavelength with a fractional CO2 laser to ensure skin resurfacing and the best possible result. Case Description For this study, 31 patients presenting vascularized acne scars were considered. They ranged between 20 and 35 years old. The therapeutical approach usually started with two dye laser treatments and two CO2 laser sessions. In this study, the dye laser was mainly used for the resolution of skin inflammation and vascularization while CO2 was used for skin remodelling. To guarantee the best and safest outcome, a skin contact sensor was included with the device. Using a 4-point Global Aesthetic Improvement Scale (GAIS) (none: 0, slight: 1, mild: 2, excellent: 3) to assess the treatment outcomes, 77% of patients claimed it was “excellent”, 16% “mild” and 7% “slight”. Conclusions The combination of different laser devices can be a promising therapeutic alternative for acne resolution. Remodelling the skin with the CO2 laser wavelength and reducing the inflammation and vascularization with the dye laser could be particularly helpful, especially for patients…
How strong is the evidence?
Evidence Hub reads this as a case series, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health. Reported size: 31 participants or records.
