Effect of CO2 fractional laser combined with recombinant human epidermal growth factor gel on skin barrier and serum C-reactive protein in acne scars

Among them, 51 patients who received CO2 fractional laser treatment alone were assigned to the control group, while 54 patients who received a combination of CO2 fractional laser and rhEGF gel were assigned to the observation group. We assessed treatment efficacy, symptom relief time, skin barrier-related parameters, pre- and post-treatment inflammatory factors, treatment-related adverse reactions, quality of life two months post-treatment, and treatment satisfaction in both groups.
