[摘要]目的：探讨含百脉根籽提取物(Loutus Corniculatus seed Extract， LCE)的产品治疗面部轻中度痤疮的临床疗效。方法：将90例面部轻中度痤疮患者依据治疗措施不同进行分组，LCE安瓶组(观察1组)、LCE安瓶及LCE喷雾组(观察2组)和不含LCE的安瓶组(对照组)各30例。观察三组患者皮损疗效、痤疮(炎性丘疹)部位毛孔数量和单个痤疮体积的变化。结果：治疗4周后，观察1组和观察2组皮损总有效率高于对照组，单个痤疮体积值及皮肤毛孔数量值的减少率优于对照组，差异均有统计学意义(P<0.05)。结论：以百脈根籽提取物为有效成分的LCE安瓶及喷雾治疗面部轻中度痤疮疗效显著，能有效改善痤疮体积及毛孔数量，可在临床推广应用。
