I have stubborn and pesky pimples on my cheeks and forehead, i have tried everything like tablets,ointment and even home remedies nothing works, it been 2 months, every day i wake up with a new one. I want to know the reason, why i am facing it? I wash my face 4 to 5 times( with cold water) I am having proper diet(home food) less oily and drinking 3 liter water daily, then why? Ps: i have oily skin.
