Thermage is known for skin tightening, reducing fat and stimulating collagen production. There are some immediate results after the procedure, but for the ultimate improvement may take up to 6 months. Thermage results usually last for about 18 months and maintenance treatments are necessary, as we age. Side effects are rare but there is a chance of blistering or scabbing, when too much energy is delivered to the skin. Thermage is the best option for people who are not ready for surgery, but the results vary by individuals and cannot be predicted.
