Age and environmental factors reduce the body's ability to regenerate collagen fibers, resulting in fine lines, wrinkles, dark circles and crow's feet. The PenSonic by Dermatouch uses ions and micro-vibrations to produce a mild, non-invasive, electric current. It has a smooth dome-shaped-roller that easily glides around the skin and is equipped with a small compartment, to be filled with the Dermatouch Energy Repair Serum enriched with a unique blend of herbal extracts, natural humectants and Creatine. Creatine is an organic acid occurring naturally in humans that helps to supply energy to all of the body's cells. It provides energy to muscle tissue can revitalize and stimulate skin cells. As we age natural production of Creatine diminishes, causing the body to show signs of aging. Adding Creatine directly on skin is very effective at stimulating the cells, protecting the skin and adding lost moisture.
