Hi, As per your complaint pimples can occur due to causes like : - Clogged pores. - Oily skin. - Hormonal imbalances. - Bacterial infection. - Inflammation. - Excess sun exposure etc. On the other hands, dark or black spots left on the face seems to be due to post inflammatory hyperpigmentation that occurs due to pimples. He should consult a Dermatologist and get evaluated and he can advise you to wash your face with a Salicylic acid containing facewash. Apply a topical ointment containing Clindamycin and Benzoyl Peroxide. Apply retinoids like Adapalene gel in a thin layer on pimples. Do cool compresses over the face. Exfoliate your face twice a week to unclog the pores and remove dead skin. You can also apply a sunscreen lotion when exposed to the sun. Oral Medication like antibiotics like Clindamycin or Minocycline and retinoid like Isotretinoin can also be advised. Avoid oily food.
