Objective To analyze the value of recombinant human stem 3 dot matrix CO₂ laser combined with ultrasound guided epidermal growth factor in the treatment of acne scars. Method 68 patients with acne scars admitted to our hospital were selected as the research subjects and randomly divided into a control group (34 cases treated with recombinant human stem 3 dot matrix CO₂ laser) and an observation group (34 cases treated with ultrasound induced epidermal growth factor). Analyze the treatment effects of both groups. Result Both groups of patients achieved certain results after receiving treatment, but the observation group showed better symptom improvement time, disease-related score, facial aesthetics and skin barrier function, quality of life score, and incidence of adverse reactions compared to the control group after using recombinant human stem 3 dot matrix CO₂ laser combined with ultrasound guided epidermal growth factor treatment, with statistically significant differences (P<0.05). Conclusion The use of recombinant human stem 3 dot matrix CO₂ laser combined with ultrasound guided epidermal growth factor therapy for acne scar patients can achieve better results, effectively alleviate their related symptoms, improve their skin physiological function and aesthetics, thereby improving their quality of life and reducing the risk of adverse reactions.
