Hello, Welcome to healthcare magic. I understand your concern about your skin colour and pimples. For your pimples, you could use Retino- A cream at bedtime. It is generally not associated with any long term side effects. As far as your skin colour is concerned, you must understand that it is not possible tpo make a dark person fairer. To a certain extent, you ca prevent further darkening of skin as a result of sun exposure. You could use a broad spectrum sunscreen every 4 hours. You could also get glycolic acid based chemical peels done by a qualified dermatologist. They help to lighten the acquired tanning and to lighten the skin tone to a certain extent. You could also try oral glutathione supplements under the supervision of a dermatologist. This a relatively new and is showing promising results. Hope this helps you. Take care.
