What the science says
Panthenol, a form of vitamin B5, has some evidence for helping the skin barrier, and all five studies that tested it directly found it helped skin hold more water and lose less of it 1. For dehydrated skin, panthenol also has some evidence behind it, as studies reported higher moisture, smoother feel, and less redness 2. In radiation-treated skin it slowed barrier damage, though it helped less than a steroid cream 1.
