ABSTRACT
ObjectiveTo observe the clinical effect of treating pigmentation after acne with Babai dection mask.MethodsBilateral contrasts was adopted.30 patients who had pigmentation after acnes were randomly recruited into a treatment group and a control group.The treatment group was applied with improved Babai dection mask,while the control group was addminated with honey mask.After 8 weeks of treatment,the therapeutic effects were evaluated.ResultsThe total effective rate of the treatment group was 63.33％,while the control group was 26.67％,showing significant difference (P=0.004).The subjective satisfaction rate of the treatment group was higher than the control group (P=0.002).The melanin value of normal skin and pigmentation after the treatment[the treatment group:(156.18±30.68)、(186.44±41.98); the control group:(158.95± 26.64)、(182.25 ± 44.03)]was dramatically reduced than before the treatment[the treatment group:(180.90±33.09)、(202.37±41.14) ; the control group:(179.92±32.51)、(205.37±43.31)]( P＜0.01).TEWL value of both groups[(13.97 ± 4.78)g/m2h、 (13.57 ± 3.68)g/m2h]were higher than those before treatment[(9.64± 3.01) g/m2h、(10.55± 3.39) g/m2h](P＜0.01).The treatment group (33.72± 9.89) ％ had no change in water capacity than before(35.26± 11.41)(P＞0.05),while the control group decreased[after the treatment:(32.05±10.34)％,before the treatment (37.21±12.24)％].Uv / Ue value of skin elasticity decreased in the treatment group (0.63± 0.05) while no change in the control group (0.64± 0.05).Conclusion Improved Babai dection mask had obvious effects in whitening,accelerating regression of post-inflammatory pigmentation,maintaining the water capacity,and increasing skin elasticity.
