This is probably cause by a yeast called Tinea Versicolor. It produces a fine clamber on the surface of the skin which can peel past its sell-by date when you tan and sign out behind adjectives areas. You can reduce the risk of getting this problem by using a dandruff shampoo containing zinc (e.g. Head and Shoulders) or selenium (e.g. Selsun) as a body clean a few times a week. These chemical help to preserve the yeast down.
