How to remove a pimple scar FAST????

Hi, I got a terrible pimple on my chin in late April early May this year. it went away towards the end of May I guess, but I noticed the scar around late June early July. I have been using vitamin E oil and creme since then, but it is still there (just not as large) and it makes me look like a hic. Is there anything that will actually work before Oct. 8 (picture day)?|||Makeup.|||try Scar Therapy, trust me it works. Apply 2 times a day, you should see a slight difference in just about a week
