Whats the best to prevent scarring/help healing process!?

I recently waxed my upper lip and there is a little burn mark from the wax being to hot near the corner of my mouth. I don't want it to scar, and I want the healing process to be quick. So far I've used Vaseline, Palmer's Skin Therapy Oil, and coca er. Will this work to prevent scarring? Let me know what else would be good to use. THANKS :)
