Phase I: Inflammation. Piercing the skin triggers your immune system to cleanse the wound, remove debris, increase blood flow and begin to create new tissue.
Phase II: Proliferation. The wound is rebuilt with new granulation cells, which are part of the extracellular matrix. Additionally, a new network of blood vessels develops.
Phase III: Remodeling. The wound is replaced with new dermal tissues and blood vessels.
Best of all, SkinPen works. Ninety percent of subjects in the clinical trial would recommend the procedure to family and friends.
