How to Use an Alum Block When Shaving

If you’re familiar with shaving culture and its many accessories and tools, you may have already heard of an alum block.

An alum block is a mineral block, made of potassium alum, that has a long history of use as a post-shaving tool. It can be used on the skin after shaving to stop bleeding, reduce inflammation, and more.

Let’s explore what an alum block is, how it benefits the skin after shaving, and how to use it.

An alum block is a mineral block made of potassium alum, a compound that has antiseptic and astringent properties. The antiseptic properties of the alum block offer protection against disease-causing microorganisms, while the astringent properties help reduce inflammation and bleeding.

Generally, an alum block is used after shaving to soothe the skin, prevent the spread of bacteria, and reduce bleeding associated with minor nicks and cuts. It can also be used to prevent some of the more annoying side effects of shaving, such as razor burn and ingrown hairs.

Alum block vs. styptic pencil

Both alum blocks and styptic pencils are made from alum, a compound that has many uses outside of shaving. The astringent properties of alum blocks and styptic pencils help soothe the skin after shaving.

However, while both products can be useful in your shaving routine, there are some differences in what they can do.

  • Alum blocks are usually reserved for minor cuts and nicks that may happen during shaving. They can also be used as a natural deodorant, or as a part of a skin care routine to reduce acne. The mineral block form has a longer shelf life.
  • Styptic pencils are a more traditional piece of post-shaving equipment reserved for more serious cuts. Styptic pencils aren’t just used for shaving. They also work against most types of minor bleeding. The powder pencil form may be used up more quickly than an alum block.
