This is the most effective anti-perspirant I've found to date. It beats Mitchum unscented gel by a long shot. I do find that it will leave slight white marks on my clothes if I don't let it dry for a few minutes, but not as bad as other products and never leaves that yucky white residue on the inside of my t-shirts and blouses. Unscented is the best, plus it doesn't irritate my skin, even right after shaving. I was going to take off a star for it not being 100% invisible, but it makes up for that by being so effective and gentle.
