Fat Freezing technology safely delivers precisely controlled cooling to target the fat cells underneath the skin gently and effectively while leaving the skin itself unaffected. Once the treated fat cells are crystallized ( frozen), they die and are normally processed and eliminated from the body. Once the treated fat cells are gone, they are gone for good. During this procedure, you may feel some deep pulling, tugging, pinching, numbness, or discomfort. After the procedure, typical side effects include temporary numbness, redness, swelling, bruising, firmness, tingling, stinging and pain. Many patients do experience redness in the treated areas for up to a few hours after the applicator is removed. In rare cases, this redness may persist up to 2 weeks, but it completely resolves itself.
