Just looking for a bit of false tan advice, I'm 42 and have never mastered it. I bought some of the boots gradual tanner stuff but what i don't understand is the exfoliating part. Presumably i exfoliate to get my skin ready for the tan but then if I'm putting it on every day how does it not build up on the ankles, wrists etc? Surely if i exfoliate it'll come off in those areas.
