What or how will removered marks after a pimple. I have very light skin on my face, so after I have a pimple I have these ugly red marks left over on my face, sometimes for weeks… I also have three bad red marks that will not go away. I am not sure if they are scars or soon to be scars.. They ahve been there for around 3 months.. They look horrible.. What will remove the red spots after the pimple is gone?
