People with eczema have skin that is poor at retaining moisture and insufficiently oily. The dryer it becomes the itchier it becomes, so dermatologists recommend that after showering, the affected skin be gently rubbed with Vaseline or other hypoallergenic emollients.
異位性皮膚炎患者由於皮膚的「障蔽功能」缺損，保水性差、油脂分泌不足，因此皮膚偏乾，越乾就越癢，因此，醫師建議患者在洗完澡後，最好能擦上凡士林等低過敏配方的保養品。
