Details & care

What it is: A clean, stain-free serum deodorant featuring a unique AHA blend for the ultimate odor-fighting treatment.

What it does: Your pits need an AHA moment. AHAs (Alpha Hydroxy Acids) help lower the pH in your pits so it's harder for odor-causing bacteria to live there. Less bacteria means less stink. Shikimic acid, derived from star anise which is known for antimicrobial properties, naturally helps stop odor. Mandelic acid, derived from almonds, accelerates cell turnover to visibly brighten and combat dullness and discoloration. Aloe vera juice and hyaluronic acid hydrate for smoother, softer skin. Bonus: the aluminum- and baking soda–free formula also helps prevent ingrown hairs.

Research results:
In a consumer study with 33 participants after one use:
- 97% said the product made them feel fresh
- 94% said their body odor was neutralized
- 92% said the product lasted through workouts

How to use: Shake, roll, apply liberally. Gently squeeze for more serum.

It ACTUALLY works!

We've all heard the raves and reviews about non-toxic and organic/clean deodorants working and being the best and then giving them all a shot and being mortified at the gym when they fail. I swear to you, this is the FIRST one I discovered that actually works for the whole entire day and then some. I've tried Type A, Toms, Routine, and Lume. NONE OF THEM worked. The closest to best was Routine but that would stop working at the end of the day. This one smells very light and clean, not at all poignant or in your face, feels like a serum that rolls on cool, and then somehow, miraculously tackles any and every odor that could exist. For newcomers to the clean deodorant scene, it might take a few days before it kicks in so just be a little patient. Your body's detoxing, and then after 3-4 days, this stuff is magic. I even got one for my boyfriend who tried Toms and Native and was disappointed. I sniff my armpits after a workout and nothing. After a stressful lecture and nothing. I absolutely love this an am on the third bottle.

Sorcery

Unsure how the science of this product works but wow!! No more stink for me! I was using another natural deodorant brand and that stopped working for me. I'm about 2 weeks into using this product and I am in love!

no more hormonal smelly pits !!

I’ve tried every deodorant out there. After I had my son I had very smelly armpits and nothing was masking the smell. After a couple weeks of giving this a try it I have ZERO smells coming from my armpits!! This stuff works!!

Finally a nontoxic deodorant that works!

I have tried countless deodorants in an effort to not sacrifice odor control, sweat protection, and non toxic ingredients. I bought this when I wasn't really expecting much from it. BY FAR the best nontoxic deodorant I have used. Actually controls my odor and sweat-even during hard workouts. It doesn't really have much of a scent itself, just great at keeping you not smelly or sweaty. Buy it! You will be pleasantly surprised like I was.
