Hello my pimples are leaving slowly but these pimples leaves black sign what should I do please suggest me?

Continue Rx. You're 16 now and it's time to take charge of your health even if your family hasn't been aggressive about having your acne treated. The hyperpigmentation will fade in a few weeks of months and using a hydroquinone bleach will make your face look strange. If topical benzoyl peroxide as tolerated hasn't cleared you in 2 weeks, phone your physician for prescription-strength rx.
