The Plasma Pen is an anti-aging therapy that is non-invasive and can substantially improve the appearance of the skin without requiring expensive and invasive surgery. The pen treats fibroblasts, the collagen-producing connective tissue cells in the body. Collagen is is responsible for keeping the skin taut and supple. The Plasma Pen never makes contact with the skin; instead, it stimulates the epidermal layer of the skin, stimulating the body's creating of fibroblasts.
