I recently got a very small cut on my lip. The next day, there was a large pimple there. It popped in the shower, and now there is a small puckered sore area. This has happened to my lip before, and there is now a permanent mark (a raised area that looks like a tiny pimple on my lip - it is slightly darker in color than the rest of the lip) in the previous area.

How can I prevent this "pimple" from becoming permanent as well? I have been applying peroxide several times a day to clean it, but don't know what else to do...I would not like to have another strange mark on my lip...I am already self conscious about the first one . It is a little strange-looking for a scar, but I suppose I could also apply some Neosporin in case?
