Abstract Objective: To study the clinical curative effect of tartaric acid combined with collagen dressing and CO2 fractional laser (CO2FL)in the treatment of facial spitted acne scars. Methods: 98 patients with facial spitted acne scars treated in our hospital during the period from April 2016 to April 2017 were randomly divided into the study group (49 cases) and the control group (49 cases). The two groups were treated with CO2 fractional laser and collagen dressing, and the study group were additionally treated with tartaric acid. The curative effect, Vancouver scar scale (VSS) score, time of work delays and patient's satisfaction were compared between the two groups after 4 courses of treatment. Results: There were statistically significant differences in the interaction effects of between-groups and time points (P<0.05), and ECCA scores of two groups after treatment were lower than those before treatment (P<0.05). The total effective rate after treatment of the study group was significantly higher than that of the control group (97.96% vs 83.67%) (P<0.05). The difference of VSS score before and after treatment of the study group was significantly greater than that of the control group (P<0.05). After treatment, the total satisfaction rate of the study group was significantly higher than that of the control group (93.88% vs 75.51%) (P<0.05). The mean time of work delays of the study group was significantly shorter than that of the control group (P<0.05).The incidence rate of adverse reactions in the study group was significantly lower than that in the control group (24.48% vs8.16%) (P<0.05). Conclusion: Tartaric acid combined with collagen dressing and CO2FL is effective in the treatment of facial spitted acne scars. The regimen can effectively improve the scar status of patients and shorten the time of incapacity, with high safety.
