Dear amrn:If you had silicone gel implants placed 6 years ago in the USA, then it is very likely you have the "classic" natrelle implants or memory gel implants. The good news is that since your procedure 6 years ago, we have a lot more in terms of options for silicone gel implants. I would likely suggest you consider the true gummy bear implants - the Inspira Cohesive implants. They have the highest fill-volume of all the silicone gel implants out there (meaning they are the gummiest). These newer implants will likely significantly reduce your rippling. In addition, although its hard to tell from the single view photo that you posted, I'm guessing you may have some loose skin and/or implant lateral malposition. Depending on your physical exam findings, you may need some skin tightening or sutures laterally to correct any lateral malposition. Of course a formal consultation and physical exam is needed to give you any meaningful advice. Please see a board certified PS to learn more about your options. Best wishes,Dr. BasuHouston, TX
