BACKGROUND/PURPOSE: Presently, skin-cleaning agents that claim to be removed by water or wiping alone are commercially available and have been used for the purpose of bed baths. However, there is a lack of knowledge on how water washing and wiping differently affect skin physiological functions or ceramide content. The aim of this study was to compare the effects of water washing and wiping on skin physiological functions and ceramide content.
Three kinds of the cleaning agents with different removal techniques (ie, water washing and wiping) were used in this study. Skin physiological functions (ie, transepidermal water loss, skin hydration, and skin pH) and skin ceramide content were measured before and after seven consecutive days of the application of each cleaning agent.
No significant differences in skin physiological functions or ceramide content were observed between water washing and wiping.
Cleaning agents that claim to be removed by water washing or wiping do not affect skin physiological functions or ceramide content by either removal method.
背景/目的：目前，市面上有声称仅通过水洗或擦拭即可去除的皮肤清洁产品，并已用于床上擦浴。然而，对于水洗和擦拭如何不同地影响皮肤生理功能或神经酰胺含量，人们了解不足。本研究的目的是比较水洗和擦拭对皮肤生理功能和神经酰胺含量的影响。
本研究使用了三种具有不同去除方式（即水洗和擦拭）的清洁产品。在连续七天使用每种清洁产品前后，测量皮肤生理功能（即经表皮水分流失、皮肤水合作用和皮肤pH值）以及皮肤神经酰胺含量。
水洗和擦拭之间在皮肤生理功能或神经酰胺含量方面未观察到显著差异。
声称可通过水洗或擦拭去除的清洁产品，无论采用哪种去除方法，均不会影响皮肤生理功能或神经酰胺含量。
