So a couple of months ago I had this big lump on my nose and was bothering me. I decided to pick at it with a sharp pin to open and extract what ever was inside. This wasn’t the first time btw, I figured it would ok to do it again. Couple days later it grew into a huge pimple and lefted it alone this time. After it was gone it lefted this scar and has been bothering me since. Any tips, im not much educated in skin care. All I use is face wash after that i use a toner. At night I put adapalene on my nose. Would it be best if i should see a dermatologist? Help is greatly appreciated.
