Hi You seem to be having physiological acne, which means that acne is due to the changing hormonal profile at your age. Please use a salicylic acid face wash twice a day. Using a face wash too often or scrubbing too much can dry out the skin and the oil glands actually over compensate by secreting more oil. Avoid picking at your pimples. Please eat healthy and avoid junk food. if acne persist you may need to take antibiotics so see a dermatologist
