Suggest Remedy To Get Rid Of Burn Mark On Neck

I burned my self with a curling iron almost three weeks ago. I applied honey first and kept it covered, but it healed slowly. I later applied lavender oil and myrrh and golden seal powder. It healed much quicker but the skin is much darker. Finally I dabbed some apple cider vinegar on it. I plan to apply organic coconut oil tomorrow. I dread a scar but it is healing bumpy...Help! I am African American and fear scarring on my neck/ shoulder area.
