Love It So Much

This stuff is incredible!! The Mandalic acid is not too strong for my underarms. it gave me all day odor protection, I didn’t stink at all. Although it doesn’t claim to have sweat protection, I experienced less sweat than I normally get with other aluminum free deodorants

Love!!

LOVE this deodorant. It’s pricey but it works the best for me. I love that it’s a natural deo that is effective! Tip is to use it at night!

THE BEST EVER.

My favourite deodorant EVER. I've been using this for about 3 years now and can't get enough. I see that many others have experienced rashes and other sorts of reactions. I personally have never had any issues with this. Perhaps it just doesn't work with certain skin types? I stress sweat due to anxiety and for some reason, I don't have to worry about stress sweat smell when I use this. I can go to the gym or yoga and not worry about how I smell. Amazing stuff.

BLEACHED CLOTHES

If I could give this a 0 star review I would. It actually works great as a deodorant but it BLEACHES your clothes. If you ever get any of the product on the outside of our clothes, when the sun hits it it will bleach your clothes. Ruined my favourite shirts

Worst applicator, the roll on ball tends to pop out. Not an effective formula.

It works amazing.

This works great for me. It was a 98°F out today and couldn't smell any BO on me all day. I put some on last night after taking a shower and put some more on this morning, since it was going to be a hot day. Also, I sweat at night from going thru perimenopause and still no BO!

long lasting no odor

i like this deodorant a lot. originally when using it, i thought it didn’t work for me. but i realized after applying, i need to let the deodorant set first before putting my clothes on so it doesn’t rub off. i sweat and there was no smell at the end of the day. hot tip for ppl who said it doesn’t work for them.

Don't Buy

very disappointed in the product. I was hoping for it to work but unfortunately it didn't. it didn't even last 5 hours and I could feel it wearing off and the product kept coming out of the cap. I rather use hand sanitizer. I am a rouge member and I have shopped at sephora for a long time. I def will continue to shop and I have never written a review about any product good or bad. but this product was terrible and I had to write one.
