The Eclipse MicroPen creates thousands of micro-channels which allows for superior penetration and infusion of topicals during and post-procedure without ablation or introduction of thermal energy. Fractionated injuries are a quick, safe, and effective percutaneous collagen induction therapy. Collagen Induction Therapy (CIT), or micro-needling, is the procedure by which the body’s natural response to healing is used to increase the amount of extracellular matrix such as collagen or elastin in the skin. The micro-channels created by the Eclipse MicroPen allow for leakage of blood, serum, and lymph in a controlled and temporary manner. These “injuries” are enough to initiate the wound healing cascade which is composed of three basic phases.
