how to avoid pimples and also black marks

Hello,

Welcome to the ehealthforum and I am really glad to help you out. Your concern is regarding the treatment of acne. For its treatment, keep you face clean by washing with a mild soap atleast twice a day.

Pat it dry and do not rub it. Avoid picking or pressing the acne. You can also use Benzoyl peroxide 5% lotion or gel once at bedtime. An amount of lotion the size of a pea should be enough to cover most of your face.

If the symptoms persist then topical antibiotics, topical isotretinoin and oral antibiotics may be needed. Please consult a dermatologist in that case.

It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care.
