An Alum Block, also known as an Alum Stone or Alum Crystal, is a crystal-like stone that is moistened with water and gently rubbed over the shaved area to act as an antiseptic and to combat a number of post-shaving related skin problems including razor bumps, razor burn and redness. It can also help to stop bleeding from small nicks and cuts.
The Alum block has antiseptic properties that not only cool and refresh the skin after shaving but kill surface bacteria too.
An Alum crystal is ideal for those who wish to use a natural antiperspirant. Apply the Alum stone to the underarms for a reliable, alcohol free antiperspirant. Alum Blocks are non-scented so you can still use your favourite scented deodorant.
Alum Blocks are highly effective in controlling excess sweating.
