At one point I dabbled with a body scrub, which ended up being a huge pain. The apricot pit bits got wedged into my shower floor and clogged up the drain. Alternative?
Earth Therapeutics Hydro Gloves easily exfoliate skin. Add a squirt of body wash or rub 'em against some bar soap, and they lather up beautifully.
There are also exfoliating bath towels, which are longer to make back scrubbing easy, like the Salux Nylon Japanese Beauty Skin Bath Wash Cloth/Towel. They are quite loved, but I don't find them as easily negotiable as the gloves.
This idea can also be for the dudes. Don't be afraid of polishing the skin, men! (No one has to know. Or that you follow up with moisturizer afterward.)
