Coolsculpting is the gold standard for non-invasive permanent fat reduction in a targeting area. It works wonders on destroying the fat cells to give the treated area a more sculpted look; however, it does not treat skin elasticity. Based upon your current skin condition, the procedure may make the appearance of sagging skin or stretch marks appear more predominant since the fat tissue is not there to occupy the space. Since the elimination of fat cells happen gradually over 16 weeks, your skin does have time to adjust but if you already have sagging skin prior it may become worse. A consultation with a certified CoolSculpting specialist will help you determine your options and the possibility. There are other non-invasive treatments that can be done after CoolSculpting, such as radio frequency and infrared heat, to aid in tightening the skin. Additionally, you can take collagen supplements to help in improving skin elasticity along with keeping your body hydrated. Hope this helps, Dr. Pushpendra K. Jain, MD
