My skin tans like that's its job. I hate it. I'll be out wearing sandals and immediately get a tan line across my foot. I get the raccoon eyes really badly too. This year I'm trying to be diligent about the sunscreen and for the most part it's worked. I even bought myself that aerosol-like sunscreen spray from Coppertone. It helps to get all those places like my shoulders and back that I can't reach myself otherwise. So far I'm good with no tan lines on my hands nor on my legs this year and nothing too noticeable on my upper body unless I'm wearing a strappy shirt or dress.
