Kosas Chemistry Deodorant - Aluminium and Baking Soda Free + BO-Fighting AHA Serum that Exfoliates, Softens, and Nourishes the Skin, (Beachy Clean)

Pleased that it works - eliminates odor and hydrates

Im glad i chose the unscented, but the consistency is watery and i might finish this one sooner... hope the brightening the skin claim is true, not seeing result yet, but overall its ok

The scent of the blue option is not great. Very chemical and overpowering. I’ve tried the white one and it’s much better.

Does not work

I had to return it as it was an opened package received. The fact that I was unable to use it disappointed me, even though I was eager to use and review it.

Kosas Chemistry is the best! Works great, feels fresh, and super gentle.

I rarely write reviews this long, but this deodorant genuinely deserves it because I know there are women out there going through EXACTLY what I went through and thinking they are losing their minds.For context: I have been anti-aluminum deodorants for almost 10 years.I switched years ago to potassium alum crystal deodorants/alum stone because I personally preferred avoiding traditional antiperspirants. I eventually even used the alum stone in roll-ons and sprays form. That worked for me for YEARS.Then life changed. I moved, no longer had access to my usual setup, and decided to start exploring the “best” aluminum-free deodorants on the market because I was also interested in finding something with fragrance that still worked well.That turned into a VERY expensive and frustrating experiment. Over the 2 years. I have tried what feels like every viral natural deodorant on the market.Here are the major ones I personally tried:• Native• Lume• Salt & Stone• Nécessaire• Schmidt’s• Donna Karan Cashmere Mist aluminum-free versions• OUAI St. Barts deodorant• multiple UK natural deodorants• random clean beauty brands from stores and airports while travelingSome were better than others, but NONE solved the actual issue.And this is where I need women, especially women in perimenopause or women dealing with hormone fluctuations, to really pay attention. My issue was NOT regular daytime sweat.Most aluminum-free deodorants seemed “fine” during the day because I rarely sweat not in the hot or cold weather.The real test was NIGHT SWEATS.I would wake up in the middle of the night and immediately smell myself.And not just “normal sweat.”It was a very specific hormonal smell that seemed to happen especially during:• hot flashes/night sweats• hormonal fluctuations• progesterone use• stress sweating• perimenopause symptomsAt one point I was bathing 2–3 times a day because I genuinely thought something was wrong with me.Some deodorants actually made it WORSE.I noticed that certain natural deodorants mixed with sweat overnight and somehow amplified the odor by morning.Lume personally was the worst experience FOR ME. I know some people love it, but my body chemistry absolutely hated it.Native did not work for me either.Salt & Stone smelled beautiful initially but did not survive hormonal sweating.Nécessaire was decent, but left a tacky film under my arms that I could constantly feel.OUAI St. Barts smelled amazing in the tube, but on me it mostly left a white/tacky residue under my armpits and still did not solve the actual odor issue.Donna Karan Cashmere Mist gave strong fragrance coverage, but honestly it felt more like perfume masking odor rather than actually stopping the odor process itself.Then I started noticing something VERY specific:Whenever I took progesterone capsules, the odor became dramatically worse overnight.And bizarrely, it was mostly my RIGHT armpit.I thought I was imagining it.I would wake up and instantly notice the smell even after showering before bed.It got so bad that I became reluctant to even continue progesterone because the odor change was THAT noticeable.Then I found Kosas Chemistry.And THIS is where everything changed.The first thing I noticed was that this product works completely differently from most natural deodorants.Most aluminum-free deodorants rely on:baking sodacharcoalmagnesiumstarchesfragrance oilsThose ingredients mainly:absorb moisturecover odoror try to neutralize odor temporarilyBut Kosas Chemistry seems to actually change the underarm environment itself.The key ingredients are:Madelic AcidLactic AcidShikimic AcidThese are acids commonly used in skincare.After researching it, I realized WHY this worked when everything else failed.Hormonal sweat is different.Perimenopause, progesterone, stress sweating, hot flashes, and hormonal fluctuations can change:skin pHbacteria levelssweat compositionoil production and the underarm microbiomeThis deodorant appears to work by lowering the skin’s pH so odor-causing bacteria cannot thrive as easily.That is COMPLETELY different from simply masking smell.And I can literally FEEL the difference.The real test for me was sleeping.The first night I used this:No odor.Second night:Still no odor.Then I tested it again with progesterone because I honestly could not believe it.Still no odor.At that point I knew this product was fundamentally different from every other aluminum-free deodorant I had tried.There was even a day I:exercisedcleaned all daysweat heavilydelayed showering for hoursAnd I STILL did not have the horrible hormonal odor I had been struggling with.That NEVER happened with the other brands.What I also appreciate:no overwhelming fragrance bombno thick suffocating feelingno heavy greasy layerno tacky residue like some cream deodorantsno “trying to cover sweat with perfume” effectIt genuinely feels more like underarm skincare than deodorant.And honestly, I think that is why it works.If you are someone who:thinks all natural deodorants failsmells worse at night than during the dayexperiences hormonal body odoris in perimenopauseis taking progesteronegets hot flashes/night sweatsnotices odor changes linked to hormonesPLEASE consider trying this before giving up on aluminum-free deodorants entirely.I genuinely wish I found this sooner because I wasted so much money trying products that simply were not designed for hormonal odor chemistry.This is the first aluminum-free deodorant in YEARS that made me feel normal again.Easy 5 stars.

حلوووو مرهمشكلته الوحيدة انه يطول على ماينشف لانه رول سايلوريحته مش ولا بد بس على الجسم حلو جدًا ماله ريحة ولا لون مزعج ومفعوله يستمر مدة طويلةانصح بإستخدامه

Best deodorant I've ever used. Been using it for a few weeks and it's been great. The scent is extremely subtle and is gone very quickly. So it's not the kind of deodorant that masks odors. It just straight up prevents them from existing.Anti-perspirants don't really work for me and they tend to stain my clothes, so I opted for deodorants years ago. Baking soda irritates my skin, so can't do those. Also get irritated by certain fragrances. Kosas doesn't irritate my skin. And I sweat plenty - workouts, yard work, sun bathing - I've never caught any foul odors. I rarely go 24 hours without a shower, so I can't vouch for any extended protection. But I've used several acidified deodorants - even stridex pads - and this is the best. The last acidified deodorant I used (lume) didn't work for long, maybe a few hours, and the fragrances were nauseating. Kosas is the real deal.The only cons I can think of are: shaking - you need to shake it, since the mixture likely settles or separates in the bottle. Not a big deal. Also, it's a liquid serum. It's gonna be wet. I apply a light layer, and give it 60 seconds - it's usually dry by then. Maybe a tad sticky, but I don't notice - I'm a guy, so maybe the hair helps mask that.The biggest knock I have is the cost. I thought about docking a star for the price, but it works too good. If I ever find a cheaper option that works this well, I'll jump ship in a heartbeat. But for now, I'm sticking with Kosas.

طالبه بدون رائحة جان نوع اخر ومعطر ؟؟!

I did a lot of research until I found this product. It is a healthy deodorant without random chemicals, does not leave a stain on your clothes, does not smell and most importantly it works! Many healthy Aluminum free deodorants do not work actually but this one does. I have been using it before workout and I am so satisfied with it. Totally recommend.
