Acne or  pimples... Due to hormonal changes..Oily skin causes it...Common in adolescent age...May occur in adults also.. Food like Oily foods, ice cream, chocolate and sweets increase it.. Treatment depends on the grade of pimples or acne..So, please  send photos as it's a must to see which grade of pimples or acne for accurate diagnosis and treatment.

The severity of acne dictates the choice of treatment. In the early grades of acne even the cream might suffice however in moderate to higher grades tablets also need to be taken. The treatment has to be continued for a few months otherwise the pimples would tend to return easily. Kindly do not self medicate without professional advice as that could further damage your skin. You should send me images through private online consult for a better assessment of the problem and approaching it accordingly. Hope this is helpful.
