Electronic Muscle Stimulation (or "EMS") has been used as a form of physical therapy and rehabilitation by therapists for quite some time to stimulate and strengthen muscles in their patients. In recent years the same technology has been utilized for fitness by products such as the Slendertone Flex Pro Unisex Abs to tone hard to work abdominal muscles. It has also been utilized by skin care professionals as a form of anti-aging therapy - the electrical micro currents tone the muscles of the face and increase the body's collagen output, improving the skin's elasticity and giving it a healthier, more youthful appearance.
Typically micro-current facial machines are for clinical or salon use, but there are some models such as the DPL Nuve Hand Held LED Light Therapy System that are the designed for use in the home. Compact, handheld, and powerful, the DPL is FDA approved for replenishing the youthful look and diminishes the appearance of fine lines, wrinkles, creases, furrows and crow's-feet. It uses safe, painless, low-level "Photons" to penetrate deep into the body easing pain and repairing damaged tissues. Deep Penetrating Light (DPL) is proven to relieve pain, joint aches and stiffness in just minutes a day. Unlike the facial toning machines use in clinics and salons, the DPL Nuve Hand Help LED Light Therapy System does not require additional wires and probes, so it easy to use practically anywhere.
