Clinical Effect of Dot Matrix Erbium Laser Combined with Topical Growth Factor Gel for the Treatment of Facial Acne Sunken Scar
Objective To analyze the therapeutic effect of dot matrix erbium laser combined with topical growth factor gel on patients with facial acne concave scars.Method The study subjects included 74 patients with facial acne and concave scars in our hospital from May 2021 to January 2024.According to different treatment methods,37 patients were divided into control group and 37 patients were divided into observation group.The control group was treated with lattice erbium laser,and the observation group was treated with external growth factor gel on the basis of the control group.Both groups were observed for 6 weeks,and the clinical effects were recorded.Result After 6 weeks of treatment,it was found that the total effective rate of the observation group(36/37)was 97.30％,while the control group(30/37)was 81.08％.The observation group had a higher total effective rate(P＜0.05).The comparison of scab formation time and scab shedding time between the two groups showed that the observation group took less time than the control group(P＜0.05).After 6 weeks of treatment,the ECCA scores of the two groups were compared and found to be lower than before treatment,and the observation group was lower than the control group(P＜0.05).The skin water content was significantly increased for 6 weeks(P＜0.05),and the skin oil content was significantly decreased compared with before treatment(P＜0.05).The skin water content and skin oil content of the observation group were also significantly different from the control group(P＜0.05).Conclusion In the treatment of patients with facial acne and sunken scars,the use of dot matrix erbium laser combined with external growth factor gel can shorten the time of scab formation and scab skin peeling,and has a higher therapeutic effect.It can also alleviate the clinical symptoms of patients and improve the skin barrier function of patients.
