The glowing reviews I read about this deodorant apparently didn't matter for my skin - this doesn't work on me. At all. I haven't smelled this bad since ... I can't remember when, but it's awful.
It works for about half a day, but come evening and it's like I haven't applied any deodorant at all. I just stink. Same with Kiehl's that I've also heard good things about - no effect on my skin.

It's back to using solid deodorants for me. Despite the white marks, they tend to work.

I think perhaps author of review meant "24 hour" not 48 :))) But anyhow, Its quite expensive (17$CAD) but it is worth it, it doesnt have strong smell and doesnt sting after application after shaving, very nice and light, would buy again. A+

I have had wet underarms since as long as i can remember, regardless of the weather, and i sweat while sitting without doing any activity, i think its hormonal. Anyway this actually protects me, it does work guys, now i got dry underarms, and if i do some exercise or really get stressed and hot i sweat a little its wayyy less sweat than before, now i don't need to wash my clothes like before and i can wear some colors i couldn't before because sweat was obvious on those colors, It doesn't smell even if u sweat a bit, but then i never had an odor issue i use sugaring for hair removal and i exfoliate a lot this keeps odor dead cells and bacteria at bay.
I recommend this.

I have a complicated history with deodorants. My body seems to 'get used' to them and after I've used the same one for a while it just stops working.
The positives:
I bought this because of its promised antiperspirant qualities. It keeps me from sweating, except during a tough workout but then again I don't expect that from any deodorant. It is very reliable and it takes you through an entire day without causing you any embarrassment. I've never had to reapply. I've been using it for about 6 weeks now and the deodorant is still working like a charm.
The negatives:
As several other reviews have mentioned, it takes a really long time to dry once you apply it to your skin. I have basically had to commit to the routine of applying the deodorant, then applying my makeup in my underwear while I wait for the deodorant to dry. Only then I feel okay to get dressed. Another downside is the scent. (Apparently there are unscented versions of this around but maybe not in Europe because this sure is not unscented). I actually don't dislike it, it smells fresh and clean and yes, a little bit like men's perfume, but I think I will get tired of the scent at some point very soon in the future.
All in all, I would buy this again even though it is quite expensive. It has a few drawbacks but it does what I expected it to do.

Doesn't work any better than my Nivea roll-on deodorant. I am not picky when it comes to deodorant though so someone with more sensitive skin might see a difference. I don't particularly like the scent or the packaging either. Wouldn't repurchase.

My HG deodorant. I've tried many, from drugstore staples to expensive department store options to organic stuff from the health food store. Nothing beats this one! It lasted through big presentations, all-day trips, 18h work days better than anything else I tried. I use the "sensitive" version as I find the scent of the classic one (with the green cap) off-putting. My only complaint is that as a roll-on it is not ideal for a quick touch-up.

Full disclosure: I live in Europe and I think it has a slightly different formula here than in the US

best ever! no scent, protects against odor and sweat all day and has never irritated my extremely sensitive skin, even right after shaving. doesn't leave marks on clothes and small enough to put in carry on luggage- really couldn't ask anything more from a deoderant

I like this deodorant a lot, it just works all day :) I bought it by chance and i think I am gonna repurchase it for the summer.

After reading the reviews here and searching every drugstore that according to the Vichy site sold this product, but could not find it anywhere, I ordered it through Amazon, paid $19.....and it does not work at all for me! Awful. Didn't like anything about it. Took forever to dry. Had BO after a few hours. I hate to throw it away after only 2 uses, but since it's a roll-on it seems gross to give it away. Waste of money and time running around to drugstores looking for it!

Let me start by saying, I never thought I would spend $30 on deodorant.
I shudder at $8 deodorant.

I bought this because the current deodorant I use seems to have stopped working, and I wanted something really good and unscented.
This is an incredible product!
It is the best deodorant I have ever used.
I don't know if I can buy it all the time, just due to the exorbitant price, but it was 90 degrees today in NYC, and I didn't perspire at all.
Fantastic!!
