I have both the Pellefirm and Thermage skin tightening systems. Both use radiofrequency technology to stimulate collagen production to improve skin laxity and can be used on any skin type. Pellefirm treatments show best improvement after a series of 6 treatments. Once a week for 4 weeks and then every 2 weeks for 2 additional sessions. Pellefirm treatments result in firmer skin and temporary improvement in the appearance of cellulite. This machine uses a wand that can be applied to the abdomen, arms, buttocks, thighs and it is necessary for the practitioner to achieve a certain temperature on the skin for the treatment to be effective. Thermage CPT with Total Tip Technology uses focused radiofrequency energy to deliver bulk volume heat for great efficacy. A Thermage body treatment can also be done on abdomen, arms, buttocks and thighs. Thermage only requires one treatment, but can be repeated in 6 months for greater improvement if necessary. Both treatments have no downtime, with some immediate improvement post procedure and continues to improve up to 6 months post procedure as the skin regenerates new collagen. Prices vary depending on the area treated, it is best to consult with a Board Certified Dermatologist to see which treatment is right for you and what the cost would be.
