My face hand and feet dark but my body has a fair complexion.

Thanks for your question.  The skin on our faces and hands is often exposed to the sun more often than the skin on the rest of our bodies.  As a result, the skin on our faces and hands can become a little bit darker and more tanned than the rest of our bodies.  I would suggest that you start using sunscreen daily to help prevent sun damage to your skin - this should help even out your skin tone with time.
