What is the cause for boils and tan on my face?

Skin getting darker (tanned) in the sun is something natural for all of us Indians as we are type III-V skin types (i.e. we all tan but rarely burn even on intense sunexposure). Many a times we discount trips to office or market while giving a history of sunexposure. Please clarify what clothes do you generally wear( Full sleeved shirts/half-sleeved shirt etc) and your colour before you became dark. Are you on any medications for any disease? Where exactly do you get pimples/boils on your face and your age, occupation etc. need to be known before giving correct advice. Please reply to these simple questions and I shall be in a better position to help you out.
