Diet and skin care

First time here! Great to be with friends. Been working on this issue for a long time, I'm down to single digit sores on both legs but I need help. I went a whole summer without showing my legs in public. Does anyone have advice on diet and topical skin aids? I added foods high in seratonin to my diet, that's been a benefit, but I don't know what to put on the skin directly. Any advIce and success stories greatly appreciated. Thanks! Showoff (at least I plan to by next summer)
