Observation on the Clinical Effect of 694 nm Q-Switched Ruby Lattice Laser Combined with Tranexamic Acid in the Treat-ment of Melasma
Objective To explore the clinical effect of 694 nm Q-switched ruby lattice laser combined with tranexamic acid in the treatment of melasma.Methods 62 patients with melasma were randomly divided into two groups.The control group was treated with tranexamic acid capsules,and the study group was treated with 694 nm Q-switched ruby lattice laser on the basis of the control group.The efficacy,melasma symptoms,adverse reactions and recurrence rate were compared between the two groups.Results The total effective rate of treatment of the study group was 96.77％,significantly higher than 80.65％of the control group(P＜0.05).After treatment,the MASI score of the study group was significantly lower than that of the control group(P＜0.05).During the treatment,no obvious adverse reaction occurred in the two groups.The recurrence rate of the study group was 3.23％,significantly lower than 22.58％of the control group(P＜0.05).Conclusions 694 nm Q-switched ruby lattice laser combined with tranexamic acid in the treatment of melasma has significant effect,which can obviously reduce the MASI score and recurrence rate of patients.
