Using Salt as Deodorant for Smelly Armpits- Is it Effective

I know what you are thinking. Salt as a deodorant for smelly armpits? I know! It may sound strange but as some people say, don’t knock it till you try it!

So, how do people use salt as a deodorant? And more importantly, does it work? 

Is It Effective To Use Salt For Smelly Armpits

Yes. Salt is antibacterial, which means it can kill some bacteria, including the odor-causing ones under your arms. 

By drawing the water out of some bacteria, salt effectively destroys them. Water leaves a bacteria through a process called osmosis to balance the salt concentrations on each side of its cell membrane. Bacterial proteins like enzymes cannot work without water, and the cell finally implodes.

However, some bacteria are resistant to salt and will not be killed by it.

Can You Use Salt As A Deodorant 

You can use salt to cleanse your armpits of bacteria and odor, but salt alone will not be an effective deodorant

Salt will help to keep odor-causing bacteria from building up under your arms but it will not deodorize. Additionally, using salt alone will cause your skin to become too dry. It will pull water out of your skin just like it does to bacteria. This will only cause your skin to become damaged. 

However, like always, the skincare industry has found a way to safely and effectively incorporate salt into underarm products and treatments. You can click here to learn about Salt Crystal Deodorants.

How long will salt work to keep odor away?

Salt will temporarily keep the odor away under your arms if you use it as a scrub, but more permanently if you use it in a deodorant. 

If you use it as a scrub, then bacteria will probably build up again in a few days (sooner or later depending on how much your sweat, daily activity, skin type, etc). You cannot exfoliate every day so salt scrubs will not be a permanent fix.

However, if you are using a salt (crystal) deodorant, this will be a more permanent solution. You can use your deodorant every day and this will help to keep odor away daily.

Does salt prevent armpit sweat?

Salt does not prevent armpit sweat. 

In fact, using salt under your arms may increase sweating. This is because salt will unclog your pores and over time, detox the area, leaving the pores free and open to excrete sweat. 

I know this may make you worried, but this is a good thing! Eventually, your body will adjust and the sweating will regulate.
