Ali Raza, I advise u to use any good quality gentle facial scrub and anti acne face mask. Wash your face with any good quality face wash like "Neutrogena oil free acne wash" which contains Salicylic acid tailored for oily skin 3-4 times a day. Take steam twice a week so that pores on your nose open up which will help to remove your black heads. Avoid too much use of oily lotions and creams as they may clog your pores on face and can contribute in black heads.
