An alum block is a natural healing product that’s primarily used as aftershave. Men use this block to calm sensitive skin post-shave and also heal minor nicks and cuts. These blocks are made of potassium alum and have natural antiseptic qualities. Part of a multi-step grooming routine that should be used before applying aftershave and/or face balm. Alum blocks have been used for thousands of years to calm irritated skin in a natural way. Ancillary benefits include using the block as a deodorant. Have other medical products on hand in the event you have an atypical shaving cut. Preventive qualities also help to reduce future shaving accidents.
