Maninder K, Richa R, Dinesh AP, et al. - Findings demonstrate efficacy of fractional carbon dioxide laser for non-acne facial and extra facial scars in the skin of color. More satisfactory results could be achieved through early intervention.

• This retrospective study included 42 patients with 67 scars, including post-traumatic (43), post-burn (15), post-surgical (5), and post-folliculitis (5) scars, treated during 2019–2020, to evaluate the efficacy of fractional ablative carbon dioxide laser in treatment of various types of scars other than acne scars.

• By PGA and IGA (patient and investigator global assessment), 45.4% and 32.7% of improvement was achieved, respectively.

• Scars with >50% improvement were noted in 13.43% of the scars with IGA and 41.78% with PGA.

• Better outcomes were seen for early scars, scars without hyperpigmentation, lighter skin type, post-traumatic scars.

• No significant difference was seen for other parameters such as atrophic vs hypertrophic, facial vs extra facial, linear vs non-linear, or the number of sessions.
