Tissue oil has been known to heal scars and marks – Justin Tissue oil does the job perfectly, this has been used for years and years in our family and passed on from generation to generation. My eldest son has a tracheostomy operation which left a scar on this throat – I used tissue oil for a few months which healed the scar – so much so that it is barely visible. I have seen other people who have had this operation who didn’t use anything and the scar is very visible.
