OMG! Did you know you can use Epsom salt for itchy underarms?
Yes, I’m talking about the same Epsom salt you use in foot soaks and DIY bath salts.
If you never get itchy armpits, lucky you!
But if you do—especially when nothing else works—this may be the underarm relief you’ve been searching for.
Personally, I’ve had moments where my underarms felt like they were on fire.
No sugar scrub, no soap, no lotion worked.
So one day, I thought, “If Epsom salt can deep clean my feet, maybe it can help my underarms too.”
I gave it a try. And guess what? The itching stopped. Instantly.
So I just had to share this with you—because you’re not alone in the underarm irritation struggle.

Why are my underarms itchy?
Before we dive into the Epsom salt solution, let’s talk about what might be causing your underarm itchiness in the first place.
Here are 3 common (and sneaky) culprits:
1. Leftover antiperspirant
You’d be surprised how often deodorant residue stays on your skin after a shower.
Even if you scrub, it can cling to your pores and cause irritation or clogged pores, which equals itchiness.
This is my number one trigger.
If I use an antiperspirant and forget to exfoliate the next day, my armpits act up—badly.
Pro tip: Never scratch! It can lead to painful, swollen bumps.
Instead, exfoliate gently, and if a sugar scrub doesn’t help, Epsom salt probably will.
2. Dead skin after hair removal
Whether you shave, wax, or sugar, exfoliation is a must.
After waxing, I typically use baking soda immediately, followed by sugar scrubs later in the week.
But on days I forget—or just get lazy—the itch shows up, loud and clear.
And when soapy sugar scrubs fail to calm it down, Epsom salt saves the day.
3. Wearing dirty clothes
Yes, even “kinda clean” clothes can trap bacteria, sweat, and leftover deodorant.
If you have sensitive skin like me, wearing the same top twice without washing it can lead to serious underarm irritation.
When that used to happen, I’d scratch like crazy and then wonder why bumps popped up later.
It took a while, but I finally connected the dots.
Other causes of underarm itching:
- Ingrown hairs
- Friction from shaving
- Bacterial overgrowth
- Synthetic fabrics
- Dry skin
Regardless of the cause, gentle exfoliation can help. And Epsom salt might just be your new best friend.
How To Use Epsom Salt for Itchy Underarms
Let’s get into the method that worked like a charm for me.
Mini Epsom Salt Scrub Recipe for Armpit Irritation Relief
You’ll need:
- 1 tablespoon Epsom salt (affiliate link)
- 1 teaspoon mouthwash (affiliate link) (like Listerine – the antiseptic properties help!)
Instructions:
- Mix the Epsom salt and mouthwash in a small bowl.
- Gently exfoliate your underarms using your fingertips.
- Leave it on for 1–2 minutes.
- Rinse off with lukewarm water.
- Pat dry, and moisturize if needed.
Don’t have mouthwash?
Just wet your armpits and gently rub in dry Epsom salt for a few minutes.
Then rinse.
What happens next?
After using this scrub:
- The itching stops.
- Your underarms will feel clean and smooth.
- By the next day, the irritation should be completely gone.
I honestly couldn’t believe it worked so well the first time I tried it.
Storage tips
This is more of an “emergency” single-use treatment.
But feel free to make a larger batch and store it in a jar.
Or use dry Epsom salt alone for ongoing exfoliation.
Quick FAQs
Is it safe to use Epsom salt on underarms?
Yes—when used gently and in small amounts, it’s safe for most people.
Avoid if you have cuts or broken skin.
Can I use Epsom salt after waxing?
I haven’t tried this yet, and I’d advise you to wait a few days after waxing before using it.
I’ll update you once I’ve tested it.
How often can I use this underarm scrub?
1–2 times per week or whenever the itch strikes.
Don’t overdo it, as over-exfoliating can irritate the skin further.
