My vermilion border is fading on my lower lip from ripping my cold sore scab...

This can be improved with fillers and lasers. I suggest you see an expert for an evaluation and treatment options.  Best, Dr. Emer.

I can't completely understand what you are asking but in general if you want a better vermillion border, fillers are the way to go. The corners of the mouth can be improved with filler too. 

Hi and thanks for your question. It isn't possible to give any recommendations without photos or a consultation. I would highly recommend seeing a surgeon who is certified by the American Board of Plastic Surgery. Good luck.Richard Chaffoo, MD, FACS, FICSTriple Board Certified Plastic Surgeon

You would need to do a lateral vermilion advancement on the sides to create a much more visible lip. This procedure can be done under local anesthesia in the office.
