hello as per your history ,I feel it is tanning due to exposure to sun.simple sun screen will help you out.but sunscreen should have 50 SPF.and few other causes are there which I can brief you after examining you.and for pimple marks various skin treatments like peels , dermabrasion will help you if there is scar due to pimples. Homeopathic medicines also have great role in above conditions.
