Panthenol is a form of Vitamin B5, and acts as both a humectant and an emollient. This means it attracts and retains moisture in the skin leaving it soft, smooth and more supple. It is most effective when combined with other ingredients like Hyaluronic Acid, and helps repair and maintain the skin barrier. Panthenol in general can be used on all skin types, especially by those with dry skin. Another useful benefit of this ingredient is that it is known to help heal minor skin injuries. Panthenol works best on freshly cleansed skin and then applied in either a lotion or cream format.
