What is Thermi Smooth? Through the years, our face, neck and hands reveal the signs of aging. Although there is a wide spectrum of cosmetic solutions focused on reversing these signs, patients increasingly are seeking those solutions that deliver real results without surgery. Thermi Smooth is a great, non-surgical way to achieve a solution to aging skin and a sagging neck without surgery. As the hand piece gently heats the skin's surface using dermal healing, it targets problem areas around the eyes, mouth, cheeks, neck and hands. It is gentle, non-invasive, safe, with a minimal amount of downtime (less than an hour of redness). A series of 3-4 sessions at 2-4 week intervals are recommended to achieve lasting tightening in areas not typically treated with Botox and/or fillers.
