Which treatment could help me? Velashape or Thermage/Titan? (Photo)

In my opinion VelaShape 3 is superior to Thermage. The  advantage is their technology. Today, there are no other methods available that include a combination of Bi-Polar RF, Infrared Light, Vacuum and Mechanical Massage like VelaShape™, and no other method can guarantee the clinically proven results, efficacy and safety in 4 treatments as the VelaShape™. VelaShape™ is the only non-surgical medical device cleared by the FDA for circumferential reduction.

You may be a good candidate for the combination Ultrashape and Velashape III, spaced a week apart for approximately 12 sessions. If the scar is below your bikini line, this may be the non invasive way to go. Alternatively, you may seek a surgical opinion for scar revision as well as some type of abdominoplasty depending on the degree of skin laxity. 

Thank you for posting a photo. I recommend
learning more about V-Shape; this new laser will accelerate your metabolism for
releasing fat while tightening the skin and improving its texture. Consult with
your doctor to decide which procedure is best for you.
