Hi. Pimples at your age may be common but require good care and treatment. You'll need salicylic acid based face wash, topical or oral antibiotics for a short while to kill the organisms causing the pimples and retinoids for maintenance. All of this with good care and diet will go a long way in reducing your acne. Then of course marks can b looked at. Can also certainly assess the facial hair issue also. Let Me know if you need any further assistance for the same. Take care.
