UnverifiedpH值5.5-6.5的弱酸性洁面最适合痘肌，接近皮肤天然弱酸环境，可抑制痤疮丙酸杆菌繁殖；成分表看排序，若氢氧化钠/钾+脂肪酸（硬脂酸/月桂酸/肉豆蔻酸）排在前面基本是皂基高pH配方82% similarUnverified油痘肌选'氨基酸+APG(烷基糖苷)'复配或含'水杨酸'的洁面，清洁力比纯氨基酸强又比皂基温和；油田肌可接受早氨基酸、晚皂基的搭配82% similarUnverified皂基pH值普遍在9-10之间偏碱性，干敏肌应选pH≤9或标注'弱酸性/添加甘油'的产品；油痘肌可接受pH9.5-10的清洁力79% similarUnverified氨基酸表活（月桂酰谷氨酸钠、椰油酰甘氨酸钾等排在成分表前5位）的洁面pH约5.5-6.5，比皂基（脂肪酸+氢氧化钠/氢氧化钾）更温和，干敏肌应避开皂基型79% similarUnverified低敏洗面皂优先选择pH值5.5-7的弱酸性至中性配方，传统皂基（脂肪酸钠/钾）pH普遍在9-10，对敏感肌和角质层破坏更大，选购时认准'氨基酸表活皂'或'Syndet合成皂'（如含Sodium Cocoyl Isethionate）78% similar
