I have a bad habit of scratching/rubbing my pimples and nose. I take off the white scabs (not really scabs... But things on pimples) on my pimples and the white thing on my nose that are in my pores (i'm guessing they're pores). My sister and my mom says that it's bad for my skin, and that i'll get bigger pores on my nose by doing this.
How bad is this habit...?
