Most individuals can see and feel a difference immediately after using the Galvanic Spa with the Facial Gels. Based on our clinical studies, participants were able to see results with the Galvanic Spa used with Tru Face Line Corrector and Body Shaping Gel within two and four weeks respectively. Many people notice that their hair looks more shiny and healthy within one week of using Nutriol Hair Fitness and Galvanic Spa. Results with each of the Galvanic Spa products become more visible as you continue to use the Galvanic Spa as directed.
