Hi Marci,When we first started with Thermi several years ago (in the beginning) we thought 1-2 days was enough for around the clock and then followed by night time (12 hours a day) for about a week. However, this was for Thermi alone. Liposuction causes much more swelling, and it causes bruising, which Thermi does not. This was one of the reasons, I designed and developed all these clinical protocols as Medical Director and Chairman of the Clinical Advisory Council of Thermi.So when you have both lipo and Thermi, of course, it will take longer. So it is natural to use the chin strap until the swelling begins to subside, often 7 days and sometimes 10. In our office, we also use Endermologie, which GREATLY reduces swelling, speeds healing and improves comfort.
