Highlights

A Closer Look

This premium quality French Osma alum block will help soothe irritation and razor burn after shaving. It is an all-natural astringent that helps stop minor nicks and cuts from bleeding. It is a crystal-like stone that is moistened with cold water and gently rubbed over the entire face to act as an antiseptic. Leave it on for a minute or so, then rinse it off with cold water.

Not only does it aid in soothing skin irritation, but the properties in alum also ensure that the beard bristles grow straight out from your face and neck, which prevents ingrown hairs.
