Introduction to Surgical Scars:
“Each year in the developed world 100 million patients acquire scars, some of which cause considerable problems, as a result of 55 million elective operations and 25 million operations after trauma. There are an estimated 11 million keloid scars and four million burn scars, 70% of which occur in children.”. There are 3 main types of scars:
- Excessive collagen deposits appear raised, but not to the degree observed with keloids
- Can appear as a firm, rubbery lesion or shiny, fibrous nodules
- Are characterized by extremely tight skin that can restrict your ability to move

Mechanism of Action:
- Mechanically breaks down scar tissue.
- Activates cellular enzymes known as matrix metalloproteinases, or MMPs.
- Remodels scar tissue through the proper deposition of collagen and elastin.
