Alum blocks are used to reduce redness and razor burn, and encourage faster healing of any cuts caused by wet shaving by constricting blood vessels and tightening pores.
For best results, begin by washing away any remaining shaving soap on your face. Moisten the block with cold water to assist with closing pores, then rub the block on to the area requiring post-shave comfort (external use only). When applied properly, the block should simply glide over the skin with ease and leave it feeling soft and smooth.It’s likely the user will feel a slight tingling sensation during use. This is simply due to the astringent qualities and is to be expected.
After use, rinse the alum block and pat it dry. Store back in the plastic case provided in order to keep it dry or use an alternative dry storage area. Alum blocks that are thoroughly dried after use and stored away correctly will have a longer lifespan.
