How can i heal keloid from 2nd degree burn injury?

Can be difficult: Cocoa butter massage of the scar would be my first treatment. You probably have a hypertrophic scar and not a keloid and so it will respond to this. A true keloid "overflows" the boundaries of the original burn and usually occur in people with other keloids from other injuries. If cocoa butter massage (or Mederma) is not successful, try silicone gel sheeting worn over the scar 24/7. Good Luck!

See a doctor: A true keloid needs to be dealt with by a dermatologist or plastic surgeon. Most OTC creams do not work well. Often steroids, pressure devices etc. are needed
