INCI: Panthenol

Panthenol, also known as pro-vitamin B5, is the alcohol form of pantothenic acid (vitamin B5). It is readily absorbed into the skin, where it converts to pantothenic acid and acts as a humectant by attracting and retaining moisture in the stratum corneum. It also supports the skin barrier by stimulating lipid production and promotes wound healing by encouraging fibroblast proliferation and collagen synthesis.
