Can anyone suggest something for me to try. I exfoliate fairly regularly but I moisturise my legs every day. Despite that I have 2 patches on each leg that just won’t smooth over and highlight any form of fake tan or gradual tanner. Both knees have a patch about the size of a 50 p. Same spot on both legs just under my knee cap have the same. Any miracle products or am I looking at having white spots when I tan my legs.
