I sweat a lot, especially in the summer and my armpits tend to darken. The Mitchum Roll-On’s are truly a game changer, I can go all day without breaking a sweat, staying and smelling fresh and being comfortable throughout the day. It doesn’t leave any stains on my clothes and although it hasn’t completely conquered the dark underarm areas, it has somewhat reduced them and continues to control them. Definitely an 11/10 from me. A brand and products I would highly recommend.
