What the gurus are saying

The alpha hydroxy acids and niacinamide come up again and again, so sensitive underarms need a closer look. Those acids work beneath the skin, so the takes warn that very sensitive armpits could still feel irritated, even though the formula is designed for sensitive areas. Most takes are warm, but the sticky gel feel put some gurus off.

"I've been using the Necessaire Deodorant with absolutely no trouble. I was using another deodorant that has some fragrance, but I've backed off, especially as my underarms have been a little bit on the itchier side."

"Something like the Necessaire Deodorant, this one has alpha hydroxy acids in it. It's also fragrance-free. Now if you have very sensitive armpits this could be irritating because what you're doing is you're including that acid underneath the skin, but these are formulated so that they can be for those sensitive skin areas."

"It's different than other deodorants because it contains five percent AHA, or alpha hydroxy acids, and niacinamide, and together these can significantly lighten dark spots on the skin. It has no aluminum in it, so it's aluminum free, has no baking soda, no parabens, no synthetic fragrance. It comes in this [...] glass bottle, it's a roll-on, it's clear. Necessaire is truly a great and sustainable skincare brand, and this is one of their standout products in my opinion."

"Musky vanilla Play-Doh. But it's nice. I like it a lot. And I like that it's a stick. It's creamy enough, but like the other ones were squeeze tubes and you had to rub them in. And I just like so much more convenient to just like roll on a stick. [...] I use this most often and it's so good. Like it's so good. [...] The Play-Doh maybe doesn't sound so great but it does have a really nice scent and the scent overall it just like works with all my perfumes which I really appreciate."
