OBJECTIVE

To investigate the effect and safety of PRP and Yifu combined with ultrapulsed CO lattice laser in patients with sunken acne scar.

METHODS

700 subjects were selected from the group of patients with sunken acne scar treated in our hospital from November 2010 to December 2020. They were divided into control group ( = 350) and study group ( = 350). The grouping was mainly based on the random number table method. Patients in the control group were treated with ultrapulse CO lattice laser, while those in the study group were treated with ultrapulse CO lattice laser combined with PRP and Yifu. The clinical effect, scar improvement and quality of life before and after treatment, and adverse events during treatment were compared between the two groups. The clinical effect was categorized into cure after treatment, significant effect, effective, and ineffective. The total effective rate = 1 - ineffective rate.

RESULTS

After treatment, the total effective rate of the study group (81.43%) was higher than that of the control group (70.00%). After treatment, ECCA, VSS scores, daily activities, symptoms and feelings, work and study, leisure and entertainment, interpersonal relationship, treatment status, and total scores were all lower in both groups than before treatment, and the study group was lower than the control group. During the treatment, the incidence of adverse events in the study group (17.33%) was lower than that in the control group (28.57%), < 0.05.

CONCLUSION

PRP and Yifu combined with ultrapulse CO lattice laser in the treatment of sunken acne scar can effectively improve the scar, reduce the incidence of adverse events, and the treatment effect is obvious, which can improve the quality of life of the patients.
