From Egyptian Secrets of Albertus Magnus, Joseph H. Peterson edition:
To prevent Scars or Pock Marks to remain when a Person has received Burns on any Limb or Member
St. Lawrence sat upon his steed. God, the Lord, bless his burns, that they may not grow deep into the flesh, and eat into his body fresh. In the name of God the Father, God the Son, and God the Holy Ghost. Amen.
Three times spoken, and each time, while repeating the three holy names, must be blown over the burns, from the body outwards.
