This is the device that helps eliminate the appearance of fine lines and wrinkles, while making the chin and neck appear thinner. Its medical-grade LEDs emit deep-penetrating 625nm red light that stimulates collagen production and repairs damaged tissue, or 470nm blue light that reduces inflammation, redness, and blemishes. The device also uses EMS therapy to deliver a painless electrical pulse, causing your facial muscles to rhythmically contract and release, boosting their tone. Recommended for 20 minutes a day. Includes remote control. Charges via USB; remote powered by included button cell battery. Not for use by those with a pacemaker.
