What results can I expect from skin tightening? January 24, 2023 The Renuvion skin tightening treatment is unique in that it provides both short-term and long-term results. Within a month of treatment, you will be fully healed, and you can expect a significant improvement in the tightness of the skin. This is a result of the skin tightening effects that the radiofrequency energy produces during treatment. However, the treatment also stimulates collagen production in the skin, which will continue to increase and improve the skin for months to come. So while you will enjoy some short-term improvements, you can expect gradual improvements to continue for several months after your procedure.
