Application Effect of Recombinant Human Type Ⅲ Collagen for External Application Combined with Ultra-pulse CO2 Fractional Laser in Depressed Scars of Facial Acne Treatment
Objective To explore the application effect of recombinant human type Ⅲ collagen for external application combined with ultra-pulse carbon dioxide(CO2)fractional laser in depressed scars of facial acne.Methods A total of 90 patients with depressed scars of facial acne in General Hospital of Taiyuan Iron and Steel(Group)Co.were enrolled as the research objects between March 2021 and December 2023.According to random number table method,they were divided into control group(ultra-pulse CO2 fractional laser,n=45)and study group(recombinant human type Ⅲ collagen combined with ultra-pulse CO2 fractional laser,n=45).All patients were treated for 3 months.The differences in clinical curative effect,duration of clinical symptoms,scar improvement[Vancouver Scar Scale(VSS),Echelle d'Evaluation Clinique des Cicatrices d'acne(ECCA)],adverse reactions and patients satisfaction between the two groups were compared.Results After treatment,total response rate of study group was higher than that of control group(95.56%vs.82.22%,P<0.05).The duration of clinical symptoms(erythema,pain,complete decrustation)in study group was shorter than that in control group(P<0.05).After treatment,scores of VSS and ECCA were significantly decreased in both groups,which were lower in study group than control group(P<0.05).The incidence of adverse reactions in study group was lower than that in control group(3.23%vs.10.75%,P<0.05),and total satisfaction rate was higher than that in control group(95.56%vs.77.78%,P<0.05).Conclusion Curative effect of recombinant human type Ⅲ collagen for external application combined with ultra-pulse CO2 fractional laser is significant in patients with depressed scars of facial acne,which can significantly improve scar condition and shorten overall recovery cycle,with higher patients satisfaction.
