Valuable labels were included pharmaceutical, periodical and layover effect, clinical symptoms, chloasma area, and correlation of them. Therapeutic course had 4 weeks in the first and the second stage, respectively. Clinic final effect was valued by intentional methodology. Results 106 recipients who fulfilled with inclusion criteria were divided into two groups, therapeutic group and controlling group, respectively. Effect rate of treating group arrived at 60.4% after and before the cross treatment. Therapeutic effect in the treating group was significantly superior to that in the controlling group in the end of clinic final. The pharmaceutical and the periodical effect also manifest markedly difference in this study. But there was not cross effect between the pharmaceutical and periodical effect in each group. The symptom effect has no relation with chloasma area effect, both of them also manifests line relation.
