A clinical examination will help in determining the cause of your illness. Acne occurs due to an overactivity and plugging of the oil glands. The main cause of acne is increased levels of hormones during adolescence. It is suggested to keep your face clean by washing with a mild soap at least twice a day. Avoid picking or pressing the acne .You can also use Benzoyl peroxide 5% lotion or gel once at bedtime. For severe acne oral antibiotics may be needed. It is suggested to consult a dermatologist since the exact treatment can be recommended only after a clinical examination. I hope it helps. Take care and regards.
