If D-Panthenol were a rapper he would be called D-Panther. In Dermatology circles (where he usually hangs out), this cool cat is sometimes called pro-vitamin B5.
D-Panthenol is used in formulas because it supports the skin’s barrier function thus improving hydration. As well as this it supports fibroblasts, the cells that create collagen.
When Panthenol is applied topically, it penetrates into lower skin layers, is absorbed into skin cells and processed into Pantothenic Acid (commonly known as Vitamin B5). Because it is absorbed deeply into the skin, it adds essential moisture and also has an anti-inflammatory effect. Bonus!
