What Is an Alum Block

What Is an Alum Block

Alum block is a compound or stone that looks much like a stone. When moistened with water and softly applied to the shaving area, it acts as an astringent and also has the ability to counteract razor burn.

It can also stymie bleeding from small cuts and nicks on the face’s many contours.

Alum blocks are also used for their antiseptic properties. This means that the best alum block will not only leave your skin feeling refreshed and cooled after shaving but eliminate harmful surface bacteria as well.

History of the Alum Block

Alum block has been used by cultures all over the world for millennia. It was first used over four thousand years ago by the ancient Egyptians.

The best alum block could be considered the original aftershave. It contains mineral salts, which the ancient Egyptians utilized for its healing and antiseptic properties.

Since that time, alum blocks have been used for shaving as well and continue to be a popular item for the avid shavers, like shavettes and safety razor blades.

Benefits of Using an Alum Block

Benefits of Using an Alum Block

There are many great benefits to using the best alum block, particularly its antibacterial properties.

Beyond keeping the skin generally clean, those who suffer from acne will find that the minerals in the block may help to clear the skin.

This is especially beneficial if you have to shave in areas that break out easily.

Those areas can be a nightmare to shave and leave you in pain afterward. Furthermore, constantly shaving over and cutting into acne spots can cause scarring in those areas, and the best alum block can help prevent that, similar to the styptic pencil.

Those with naturally greasy skin will also see an improvement in their skin complexion. Simply apply the block to greasy spots and watch the grease disappear!

Those with acne and other breakouts should use it right before going to bed for the best results.

Note that the block should not be used every day as it can cause drying and cracking or else cause the skin to produce even more oils.

One of the greatest benefits of the best alum block is that it works to combat bleeding from cuts and nicks.

The salt that occurs naturally in the alum block coagulates and stops the bleeding process in its tracks. No more discovering those blood red and brown stains on your nice white Oxford ever again!

A Natural Alternative to Deodorant / Antiperspirant

Because of the bar’s natural ability to dry the skin, the best alum block has been used for centuries in the Middle East and Asia.

A Natural Alternative to Deodorant / Antiperspirant

Apply the bar to the armpits and experience an all-natural alternative to being sweat-free and smelling great!

In the same way, the alum block prevents bleeding skin after a shave, the salts work to prevent pores from producing and excreting sweat.

If you already use deodorant and want to stop the sweating as well, the alum block has no scent and will not conflict with your favorite bar.

Use Alum After Getting Your Skin Waxed

If you are getting any type of wax treatment done, use alum block to the affected area after the procedure. Remember that it is safe for sensitive areas of the body.

How to Use Alum Block During the Shaving Process

To be clear, the alum block is used as an aftershave tool, not before. It is not used to clean the face, and it is not the best face wash for men. The whole point is to rub it into the freshly shaved area.

There are several steps to consider when using the alum blocks. Be sure to heed these instructions carefully in order to get the best shaving experience.

Step 1

Get the alum block wet with water. It is best to use cold water when wetting the block.

Step 2

Rub the wetted bar onto the newly shaved skin. Be gentle in this process. You do not want to rub it in so hard that it irritates the skin.

Step 4

Once the entire shaved area has been thoroughly covered with an alum block, let it dry on the skin for a minute or two.

Step 3

Rinse any excess product off your face if you are going to apply beard oil or beard balm to your face. Be sure to pat your face dry before applying the oil.

Step 4

After using the bar, clean excess lather off the bar to keep it from building up scum. Dry the bar off and keep the bar in a cool dry place that breathes well.

How to Dry Your Alum Block

Drying your alum block is very easy. After each use, make sure to rinse the block off with water. This prevents the bar from building up grime over time.

Furthermore, you do not want the moisture on the bar to attract bacteria, mildew, or mold. After you have thoroughly rinsed it off, simply take a dry towel or cloth to the bar.

Do not rub it dry but pat it dry. This prevents the towel from wiping off more alum and wearing the bar down more quickly.

Is It Safe to Use on My Skin (Those with Sensitive Skin Beware)

For most people, the best alum block will prove to enhance their shaving experience and provide healthful benefits in the process.

However, it should be noted that the astringent properties of the salts in the alum block may be contraindicative to sensitive skin.

People with very sensitive skin should experiment with a small portion before investing in a full-size bar. The best razor for sensitive skin should be used in the process.

The best way to do this is to ask for it at your local barbershop. This will allow you to see if it will work for you. As for general safety, the answer is yes, it is safe to use, but with caveats.

Alum block contains salts, and excessive use can lead to adverse effects in the skin. For starters, the drying nature of the salts can cause the skin to crack and become easily irritated over time.

If the skin is too dry, your skin may counteract this by producing an overabundance of sweat and oil. This will make your skin appear greasy even after using the alum block.

Lastly, for those with sensitive skin, it is not recommended for daily use.

Even if you shave daily, it is best to only use it every couple of days. If you have been using it daily, just think about how much longer your bar will last by switching to occasional use!

Other Uses

Another benefit of utilizing alum blocks is that they are a great indicator of just how well (or not) you shaved. Alum blocks have a distinct tingling sensation when applied to areas where the skin is either bleeding or lacerated.

If you feel this sensation even in areas where no bleeding is occurring, it may be an indicator that your razor is dull, or you need to take better care of how you shave.

Essentially, if you shaved with a sharp razor and stroked the blade in the proper order, the tingling sensation should be at a minimum and there shouldn’t be any razor burn.

However, if you were not gentle with the strokes and used a dull blade, the sting sensation will be prominent. Thus, the alum block is great for telling you that it is time to change out a blade.

Things to Consider

While it is probably very unlikely, it is best to see what if any allergic reactions might be associated with alum block.

If you already suffer from skin allergies, it is best to speak with your doctor before using an alum block as it may cause damage and pain to the skin.
