这个是美版的duo吗？

对于炎性痘效果很好，因此降低了留疤的可能。相较其他的过氧化苯甲酰产品而言，理肤泉的这个算是成分很考究的了，但是过氧化苯甲酰就是过氧化苯甲酰啦，该刺激还是会刺激啦！都说皮肤会习惯它，刺激会逐渐降低，但就算是断断续续用过氧化苯甲酰好几年的我，用后还是会起皮发红。
Effective for nodule type acne, therefore reducing the risk of scarring. It has reasonably good ingredients and formulation, as compared to BPO preparations from other brands. But still it's BPO, so it's irritating. I've been using BPO creams or gels for several years, and still got flaky and red skin because of it.
