SkinPen® Precision and Surgical Scars

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:

Hypertrophic Scars:

  • Excessive collagen deposits appear raised, but not to the degree observed with keloids

Keloid Scars:

  • Can appear as a firm, rubbery lesion or shiny, fibrous nodules

Contracture Scars:

  • 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.
