5/5. This actually really works! It has totally improved the appearance of my underarms.
I've been using this for a bit over two weeks now, i haven't notices a complexion change under my armpits yet but it's a good deodorant.
I like this. You're not going to see a difference right away (at least I didn't) but I've been using it for a couple of months now and the skin under my arms is lighter then before.
I took 'before' pictures to prove it, lol. It's still darker then other skin on my arms so I will continue to use it and hope for the best.
