The Trinity+ tool uses microcurrent technology to stimulate facial muscles, resulting in a firmer, more youthful appearance with consistent use. By sending low-level currents through layers of skin on the face and neck, it works to tone and tighten the underlying facial muscles, in turn firming the areas of the face (jawline, cheeks, forehead) that tend to sag over time. In short, it’s like a customized fitness routine for your face.
