Can anyone recommend a relatively abrasive exfoliator for my rhinoceros hide? I want to start putting some light fake tan on and need a decent exfoliator to prep with. My skin is pretty tough around the elbows etc and I want to avoid streaks! I was previously using the Body Shop exfoliators in the tubs but the last one I bought was very oily and far too few 'scrubby bits' (technical term) in it!
