Why we stand behind it

This clean, stain-free serum deodorant features a unique AHA blend that keeps you from smelling, but also visibly brightens the darker under arm area and helps with ingrown hairs. No aluminum. No baking soda. Only skin-nourishing ingredients.

Key ingredients

Shikimic acid: a natural deodorizer derived from Star Anise.
Mandelic acid: a gentle AHA derived from bitter almonds that supports cell turnover to help address dullness and discoloration.
Lactic acid: exfoliates while helping to improve the skin′s natural moisture factor, keeping the good moisture in.

What is an undertone?

An undertone is the color beneath the surface of your skin, which never changes (even with a tan). There are three types of undertones:

Pink/Cool

I see red or pink undertones around the perimeter of my face and neck.
My skin burns easily, but barely tans.
My skin looks better in silver jewelry than gold.

Neutral

I see both pink and yellow undertones around the perimeter of my face and neck.
My skin sometimes burns and sometimes tans.
My skin looks good in both gold and silver jewelry.

Yellow/Warm

I see yellow or golden undertones around the perimeter of my face and neck.
My skin rarely burns, but tans easily.
My skin looks better in gold jewelry than silver.

Reviews

Didn't Work For Me

"I wanted to love this so bad as I heard great reviews but unfortunately this just did not work on me at all through the day. Love the packaging & scent."

— Marlena C. (2/5)

Good hope it keeps working

"Been using this for six months now. Really liked it in the beginning but now I’m not sure if my body’s getting used to it and the effectiveness is wearing off. It definitely still does the job and the first day I wear it I have nothing to worry about. Truly a godsend for me I just hope it keeps working."

— Chloe L. (4/5)

Best clean deodorant!

"I've repurchased this item four times and will continue to order it. It's the most effective clean deodorant I've tried and I love that there's no residue since it's not a stick. 10/10"

— Leah R. (5/5)

bad bad bad

"oh my god the smell I was emitting could clear a room. I'm sorry but if this works for you that is because you do not sweat or smell at all."

— s (2/5)

Best deodorant

"Repurchased several times and will never not use"

— Carolyn H. (5/5)

Highly recommend

"I was happy to discover that the deodorant is truly odorless. I really like the combination of tube and roller - it's the most convenient application I've ever used. I bought one for myself and one for my husband. I was very impressed that for both of us the deodorant lasted a whole day."

— Rebecca E. (5/5)

Pretty good but not my fav

"On my search for clean deodorants I gave this one a try but didn’t end up landing on it as my go to! I love that it doesn’t leave armpits chalky like most do but felt like it didn’t last as long as I wanted"

— Rebecca (4/5)

love this

"I've tried so many natural deodorants and this is the only one that I keep coming back to. It doesn't leave any white marks on clothing and works so well."

— h (5/5)

Didn't work for me

"I'm pretty sweaty and this didn't work for me sadly"

— Maura (2/5)

THE BEST

"Best nontox deodorant I have tried and I have tried A LOT. This is the only that works and without even needing to reapply. I used it while attending a music festival and still smelled fresh as a daisy at the end of it. I use the fragrance free version."

— Ali (5/5)
