Skin Care Products

I know that this is a really strange question, but there is a reason why I’m asking it. I’m of Cherokee, English, Irish, German, Scottish, and French extraction. Most people would consider me white, but many can tell that I have Native American ancestry, because I have high cheekbones, dark eyes and hair, and a slightly olive complexion. A guy asked me recently if I had Native American ancestry, because he thought that I sort of looked like it. He also said that I had a nice, clear complexion, and he said that Native Americans often had clear skin. Is this true? I was just wondering, because my skin is actually oily and acne-prone, but I try to take good care of it by exfoliating every day and using various skin care products. So far, my attempts to keep my skin clear have been pretty successful. What are your experiences, though? Do Native Americans normally have clear complexions, or do they sometimes just get zits like a lot of other people do?
