The glasses combine EMS (electrical muscle stimulation) and red LED light therapy to target the appearance of fine lines, wrinkles, dark circles and puffiness around your eyes. Just pop them on and let the technology do the work while you relax. The rechargeable design means no fuss with replacing batteries. Choose from 3 intensity settings (low, medium, high) to suit your comfort level. The hands-free approach gives you freedom to catch up on emails, read or simply unwind while treating your under-eye area. The electrical muscle stimulation is designed to work on the delicate skin around your eyes. Red light therapy complements the EMS function for a dual-action approach. Recharge when needed and you are ready to go again. It is a straightforward addition to your skincare routine without the ongoing cost of creams and serums. Gel must be applied under the eye to feel the microcurrent.
