This massage roller mimics the kneading movements of a beauty therapist’s hands. It supposedly helps to give you a more defined jawline and firmer skin, improves blood circulation and lymphatic drainage, and reduces water retention. I roll along the chin (with not too much force), and fit the beauty device firmly between the flesh of the double chin. I use it about 20 times on each side. Just started using it, hope to obtain a V-shaped face soon.
