I go to the beach and believe me, that is the best way to tan. But I will admit that in the winter I miss my tan. Maybe if most products didn't give such a FAKE tan I would consider using one in the Winter. But it would have to be a "natural" tan if you know what I mean. I also wear my nails short. I always clean my nails and when they grow to long, the cleaning makes them see through. And then in the end I cut them off.
