I have Pimple Problems?

I do not eat chocolate, wear makeup about once a month, eat very healthily and always moisturise/exfoliate/cleanse every night. I am female and I keep getting pimples - everywhere! All over my face! My parents never had a lot of pimples or acne and I don't understand. I put clearasil on them each night too, and they don't go anywhere, in fact more come. Can someone please help me?
