Female in late teens - I'm looking for advice on how to treat this almost 3 year old burn scar from a chemical burn from allergy shot administered by a nurse. We followed burn surgeons recommendations and the skin never healed properly. There is scar tissue underneath the skin which makes it puff out a bit. The skin never came back to normal. Right now we are just focused on regular massages with a scar oil. 2 plastic surgeons recommended cutting into the scar and making it a linear scar.
