這個是美版的duo嗎？

對於炎性痘效果很好，因此降低了留疤的可能。相較其他的過氧化苯甲酰產品而言，理膚泉的這個算是成分很考究的了，但是過氧化苯甲酰就是過氧化苯甲酰啦，該刺激還是會刺激啦！都說皮膚會習慣它，刺激會逐漸降低，但就算是斷斷續續用過氧化苯甲酰好幾年的我，用后還是會起皮發紅。
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.
