The patients in the control group were treated with 2% hydroquinone cream phonophoresis, and those in the treatment group received 2% hydroquinone cream phonophoresis and Sedum freckle capsules, both for 2 months. The symptom and lesion score were usedto evaluate the clinical efficacy. ResultsThe cure rates were 81.00% in the treatment group and 67.50% (χ2=4.320,P=0.038) in the control group at the end of treatment, 92.0% and 76.3% (χ2=5.538,P=0.019) at 2 months follow-up. The total lesion scores at the end of treatment and at 2 months follow-up were significantly lower than before the treatment in the treatment group (1.61 ± 0.84 and 1.30 ± 0.85vs.3.48 ± 1.02;t=14.152, 16.419, allP<0.01) and also in the control group (2.04 ± 0.61 and 2.03 ± 0.51vs.3.45 ± 1.09;t=10.097, 10.554, allP<0.01).
