The EMS microcurrent tightens the skin with high frequency microcurrents to tighten muscles, prevent skin sagging, and reduce wrinkles. Electrical muscle stimulation (EMS) is an ideal treatment for toning muscles and tightening the skin. It uses microcurrents to stimulate muscles to make them stronger, tighter, and leaner. The LED red light can promote micro circulation around the eyes, and fine lines and dark circles. The LED Blue light reduces acne scars and shrinks pores. Four metal probes closely contact skin and deliver small current for best result. A perfect beauty tool for easy and at-home skincare.
