SYNERGIE…A CELLULITE SOLUTION! A typical Synergie treatment program consists of a series of twice-weekly sessions over a two-month period, followed by maintenance visits. Treatments last approximately 30 minutes. To ensure your comfort and preserve modesty, you will wear a body suit during treatment. Phase I treatments (twice-weekly) typically last two months, but can be modified to meet your desired results. Phase II consists of once-per-month visits to maintain desired appearance and skin tone.
