Which radio frequency treatment is best after having BBL?

Allow me to answer your question as best i can without any photos. However, please keep in mind that an in-person, or at least a virtual, consultation with physical exam is first necessary before any legitimate evaluation or final surgical recommendations can be made.

Based upon your concerns, radiofrequency therapy is probably not the answer, especially not for the buttock area. If you are okay with adding more volume and projection to the buttock, then you might want to consider buttock implants. In my experience, implants have been quite successful at improving buttock irregularities and/or “lifting” the buttock following BBL procedures. Please keep in mind that an extremely few number of board-certified plastic surgeons specialize in these buttock implants so be sure to consult with one that is reputable and experienced. Unfortunately you may have to travel long and far away from home to find this particular surgeon. Glad to help.

Easy response is NO RF therapy works let along could kill fat cells! But you did not post photos??? So very hard to give accurate advise. Maybe best to virtual consult with....

Non-surgical body contouring treatments are notorious for giving minimal results, but remain very popular because of low risk and being over sold. True long-term patient satisfaction with nonsurgical treatment for body contouring is dismal.
Radio frequency is not considered a legitimate treatment for cellulite. It’s not a rational treatment because it doesn’t treat the underlying cause.
If you want to change your body contour than most likely, do you need to be looking at surgical treatments.
If you have lots of money, and you don’t mind having treatments that give very small changes than most of these are relatively safe with the exception of some facial radio frequency treatments that can cause premature facial aging because of volume loss. All procedures have risk benefit ratios.
From what you described I don’t think non-surgical options are going to give you much noticeable difference.
Treatments that actually work well typically eventually become industry standard, and are eventually adopted by all providers.
This means if a plastic surgeon can get better results using a non-surgical treatment then either they will stop doing the surgical treatment or buy the non-surgical device and rely on that.
Without including pictures, we can’t make an assessment. Most of these treatments tend to be fairly pricey, for those who work for a living.
Recognize that the industry has a lot of hype, including “bait, and switch”.
A lot of the decisions involved in body contouring are highly emotional and most people in this field are out to make a living.
In other words, a lot of clinics in the Aesthetic medical field are not necessarily based on patient advocacy, but rather owner advocacy.
