The Eye Rejuvenator by Methode Brigitte Kettner uses a low frequency (3MHZ) microcurrent technology to decrease puffiness, reduce fine lines, and eliminate dark circles around the eyes. MBK's game changing device combines microcurrent with a special titanium tip that heats up to your internal body temperature to improve circulation, increase collagen production, and promote product penetration. Designed to treat both the upper and lower eyelid areas, but works wonders around the lips, over the nasolabial folds, and on the jawline! This treatment is equally as preventative as it is corrective, and is the only device of it's kind on the market! Try it with any of your favorite eye creams or firming serums!
