I have had two BBLs with amazing doctors who I researched for years ahead of my decision. All of the patients I've seen had incredible long lasting results. My first BBL was 4 years ago--after about 2 years of loving my results, I saw my fat distribution go back to the way it was pre-op and my butt and hips starting getting smaller. My second BBL was just a few months ago and now I see the same thing happening. My blood work comes back fine--can you think of any explanation for this?
