Please see the attachment. They are not exactly pimples but little inflated structures, no pain occurs when they are touched and it has been present since past 3 months after I got a pimple breakout. I have a skincare routine where I am applying aziderm all over face in morning and benzoyl peroxide over these structures at night, I am also using a salicylic acid facewash every 3 days and washing face with water in morning, but they are still not going away. I also tried taking isotretinoin for a month but no progress happened. These structures are present on both left and right side region around nose.
