Your body′s “smelliest“ areas, such as your underarms and feet.
Why we stand behind it
Kaia Naturals The Underarm Bar helps to manage and keep odor under control thanks to activated charcoal and apple cider vinegar. This soap bar is formulated to help refine and manage odor caused by bacteria on the skin and may enhance the power of your deodorant to withstand even the most active lifestyles!
Now bigger, the underarm bar lasts twice as long, up to 6 months. Additionally, the bar is formulated with higher levels of odor controlling charcoal, and a new triple milling process is used which eliminates the need to dry the bar between uses and prevents a mushy texture.

"This is a staple for my son who has used it for two years. It keeps him feeling fresh and it is gentle on his skin truly working. He would highly recommend this bar."
— Natalie G. (5/5)
"I use it exclusively for my underarms so that it lasts longer, Most effective when I circle the bar directly on the armpits about 20 times which makes a ton of lather. With the remaining lather, I will use it to wash the groin area and feet."
— Mary N. (4/5)
"This is a must for natural deodorant user, stinky teens/tweens, and is so worth the price. As a pungent, active person with 4 pungent, active children, and I can't say what a difference this makes. It's pricey, so we are strict about reserving it for underarm use and use ordinary soap for everything else, but it makes a HUGE difference in controlling odors. And that has a tremendous impact on everyone's self-esteem and sense of well-being. Unlike many skincare products, its effectiveness hasn't diminished over time, and we've been buying this for years, since discovering it via a free sample. I still pick up sample sizes for travel when I can--makes all the difference for hot summer weddings!"
— Kristin (5/5)
"I can’t say for sure but this actually does seem to make a bit of a difference when I use it. I don’t like the deodorant it pairs with, but I will continue using this"
— Ashley B. (4/5)
"Just saying, like everyone else, that this soap is ah-mazing! It WORKS."
— celle (5/5)
"I have been using the underarm soap for about five months almost everyday and it seems to have a mild/moderate effect on increasing body odor when used in tandem with a natural deodorant. It cleans the armpit very well leaving no residue or smell. Overall I think it’s worthwhile to try and see if it works for you."
— Sofia (4/5)
"i constantly battle underarm smell - like faintly if you get real close up in there - even with a good scrub of dr B tea tree soap there is always a little linger. not with this tho - now ppl will want to be friends with me!"
— Shauna H. (5/5)
"I use this soap every day and it is working for me. I use a natural deodorant with mandelic acid. . . I don't notice an odor anymore, so for me these two products are helping to keep me feeling fresh and confident. . . a must in Florida heat and humidity!"
— Yvonne B. (5/5)
"Nothing more to say other than this stuff really works! A constant rebuy."
— Jessica S. (5/5)
"I don't think I noticed a difference. I used this for about 3 months and didn't find a shift in the efficacy of my deodorant. I wish I did! On the upside, this has a light scent and didn't seem to irritate my eczema-prone skin."
— Rebecca W. (3/5)
