Last year I tried these and was fine for a few days then started 'peeling' off. I rang the helpline number on the back of the bottle and the lay said I needed to moisturise. So I understand the principle, exfoliate before applying tanning moisturiser. But if I exfoliate the next time before applying cream, will that just not take off the tan that's built up? I hope I'm making sense. Can someone talk me through this please, I'm very confused.
