The Fat Freezer chin and neck system is a all in one beauty device with 3 powerful modes. Use cyolipolysis technology to help sculpt your chin and neck area. Cold temperatures cause constriction in the skin, resulting in pore and blood vessel shrinkage, creating a smoother, more even-toned surface over time. They can also soothe inflammation and irritation, which is perfect for people with sensitive or red skin. Get a tighter jawline and reduce double chin? Use your device to target double chins and turkey necks. Double chins are unattractive and very hard to lose once developed. You can easily target double chin to help tighten the surrounding areas.
