Review (4/5): I'm in love.
I LOVE THIS!!! After using it for a couple of weeks, my back acne started to clear up. The only thing that I dislike is that when the water dries from dripping from it, it dries the hit pink color. So yes, the dye/color does come off. I would buy more of these in a heartbeat.
P.S. I've been using this sponge for about 3-4 months.
