  • Holy grail deodorant.
Scent: Beachy Clean
I read the reviews before purchasing and was hesitant, but went ahead anyway. I am so glad I did. After years of using Native and never feeling satisfied with the product, this deodorant has answered my prayers. I am a very active girl. This deodorant, along with nightly use of the Pacifica underarm detox scrub, is the only thing that prevents any and all body odor without the use of aluminum. Things to note: - I had no issues with the packaging, and found it to be leak proof and convenient. - I found the beachy clean scent to be very nice, however it is mild and does not linger once the deodorant dries. - I do occasionally experience a slight temporary redness after applying, usually just after shaving my underarms. I think this is to be expected since it contains AHAs. - It does not stain or bleach my clothing, which is something I had issues with while using Native. - The tube last me about 8 months. Definitely one of my best purchases of 2025. I had to put all my friends and family on too. Highly, highly recommend this product. ... show more

  • It works!!!
Scent: Serene Clean
I never write reviews. This is my first ever review on Amazon. The reason I'm writing this is because other moms who wrote reviews were the ones to help me to decide to get this. Yes, get it! It works so well. Postpartum BO has not stood a chance to this stuff. I used natural, regular big brand, every kind of deodorant. Is it wet feeling? Yes it's serum. It will dry down. The smell is faint and that's fine with me it leaves me so fresh for days!! Get it! ... show more

  • Doesn’t dry down, but prevents odor
Scent: Serene Clean
This has really worked for me! I did a test where I stopped using it and went back to my previous deodorant, and after just a day I felt like I had a BO funk. But with this, there’s no smell. I only gave 4 stars because: 1) It doesn’t dry down for me. It leaves my pits feeling swampy, but that doesn’t personally bother me because there’s no scent. 2) The out of the bottle smell is a bit off-putting, but after 5 minutes the smell goes away. If you don’t mind having damp pits, but want no smell, I’d suggest this. Worth noting: haven’t tried it in heavy sweat conditions like high humidity, heat, or activity. ... show more

  • Finally a deodorant that works!
Scent: Serene Clean
Why did you pick this product vs others?: I've been searching for something natural(ish) that actually works. I felt like I tried every deodorant and still feel like I can smell BO at the end of the day. I'm using this morning/night + an aluminum free deo and it's working great! It's been super hot this week and I still smell fresh at the end of the day! ... show more

  • Amazing
Scent: Beachy Clean
I was hesitant to purchase this because I read negative reviews first. I’m pretty sure that I have hormonal BO, maybe perimenopause. I decided what the heck it’s worth the shot since my other natural deodorant stopped working for me. I live in Hawaii so it’s hot and humid and I sweat all the time and also work on a construction site. The first time I tried this was a couple days ago when I decided to test it out on a very extreme hike. I was pleasantly surprised that I didn’t smell at all!! I was like ok, maybe I didn’t sweat that much on the hike that I thought I did and was still doubting it. I felt the big test was today, I was gonna try it before going to work. I normally apply my deodorant and night after my shower and again in the morning. I opted out of the night application and applied it in the morning instead. It has officially passed the test! There are a couple of things that I was eh about but definitely doesn’t stop me from purchasing again in the future. First, I ordered the beach scent and it does have powdery smell to it. I’m just not not use to that smell and it’s not bothersome at all. I can get use to that. Second I do use an at home IPL occasionally and since it does say to avoid sun exposure I think that means laser too. Still not a bad thing. I can wait to do the IPL after not using the deodorant for a few days. Overall I am very satisfied and found something with natural ingredients that actually work. It has me thinking if the girls with the negative reviews are not shaking it before applying like it suggests. ... show more

  • Love
Scent: Serene Clean
This works very well, I don’t smell like a fresh cut onion anymore. The only thing I dislike is my pits feel sticky, but I’ll deal with it because it’s the only deodorant that’s ever worked for me

  • Not strong enough; still smell
Scent: Serene Clean
I want to like it because I like the minimal smell and that it is “natural.” Sadly, it doesn’t work for me.
