HOW MICRONEEDLING WORKS

The SkinPen® microneedling device causes controlled micro-injuries that stimulate the body’s natural wound healing process. The micro-injuries trigger the release of cytokines and growth factors that lead to remodeling of collagen and elastin.1

There are three phases to the wound repair process:

  • Phase I: Inflammation. Piercing the skin triggers your immune system to disinfect the wounds, remove debris, increase blood flow and begin to create new tissue.
  • Phase II: Proliferation. The wound is re-built with new granulation cells, as well as a temporary (type III) collagen and elastin, which are part of the extracellular matrix. Additionally, a new network of blood vessels develops.
  • Phase III: Remodeling. The wound has been replaced with new dermal tissues and blood vessels. The type III collagen in the newly formed tissue is replaced with stronger type I collagen, which can contract to create a tightening or “shrink wrap” effect on the skin.

The results? Clinically proven improvements in the appearance of facial acne scars for people aged 22 and up.2
