為什麼神經醯胺在管理濕疹時如此重要?
genetic mutations in eczema causes the skin to produce less ceramide. as ceramide is the cement which holds the skin barrier together, insufficient ceramide means that the skin barrier is unable to function properly.
ph level is also an important factor in managing eczema. our skin barrier has a naturally acidic ph level, while soap is alkaline. when soap is used on skin with eczema, this will raise the ph level of the skin. in addition, soap strips away the skin’s natural moisturisers. this will weaken the skin barrier further.
