I recommend my patients consider a "touch up", a single additional treatment, at the 6 to 8 month mark. I've had several patients who have gone longer than a year without recurrent symptoms, who didn't feel the need for an additional session. Obviously, the degree of symptoms pretreatment may vary considerably from individual to individual, so the duration of the benefits will vary as well. Remember, the effects of the Thermiva continue to build weeks and months after the first round of treatments, increasing collagen and elastic tissue, increased circulation and sensitivity, tightening of both the external and internal tissues.
