HOW SKINPEN WORKS
The SkinPen treatment temporarily creates thousands of micro-channels which allows for superior penetration and diffusion 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.
The Science Behind SkinPen
Collagen Induction Therapy
Collagen Induction Therapy (CIT), or microneedling, 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 SkinPen 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.
- Phase One | Inflammation: Activated by piercing the dermal tissue, platelets release cytokines and growth factors which act as signals for the body’s immune system. Neutrophils and macrophages cells are sent in to disinfect the wounds, clear the debris, increase the blood supply (a process called angiogenesis), and begin the creation of fresh, new cellular and extracellular materials (the granulation process).
- Phase Two | Proliferation: In this stage, the fibroblasts (cells that make up much of the dermis and create the extracellular matrix) keratinocytes and epidermal cells continue to divide to populate the areas of damage and secrete growth factors and extracellular matrix, such as elastin and collagen.
- Phase Three | Remodeling: At this stage, the wound has been replaced with new dermal tissues and the newly formed vasculature is now matured. The collagen in the newly formed tissue is now replaced with the stronger collagen and the tissue contracts to cause a “shrink-wrap” effect of the skin.
The Versatile Design of SkinPen
The depth of the SkinPen needles can be adjusted from .25 mm up to 2.5 mm in length. This variability allows for the SkinPen provider to adjust treatments based on the patient’s anatomy (skin thickness) as well as the patient’s need (e.g., more penetration required for acne scarring).
