Treatment starts when numbing fluid is gently infiltrated under the skin in the treatment area. This makes the procedure comfortable and also constricts the blood vessels to reduce the chances of bruising. Next, the physician will make a few tiny openings so that the treatment wand can be placed under the skin. These openings are very small and normally heal up and become invisible after the treatment. The wand will then be passed under the skin, heating its inner layers and stimulating your body to produce collagen, the building block of tighter, more youthful skin. Most ThermiTight treatments last about an hour. You’ll be fitted with a gentle wrap after the procedure, and, if you’ve had a body treatment, you may be advised to wear a compression garment for a week or so after the procedure to help reduce any temporary swelling.
