Yes, the chemical reaction is your skin produces melanin (brown pigment) to help protect your skin from further damage from the UV rays. This is why humans have evolved to have dark skin in sunny tropical or sub-tropical areas. Your body also naturally produces vitamin D from the sunlight in the fat in your body under the skin and this is a chemical reaction too. So if you don't get out in the sun much you should take a vitamin D supplement or drink fortified milk or soymilk.
