I will not recommend Dr. Carlos Spera to anyone considering a Gluteal Augmentation (implants) or (liquid silicone) injections. This called doctor had ruined my life. I had a gluteal augmentation (buttock implants) in March 2018 and a revision in 2019 with injections of liquid silicone performed. In November of 2019 after months complaining of excruciating pain and unable to function or walk, I was rushed to the emergency room septic of the infection in my left implant. Please do not even think because he has a great marketing strategy that he is a professional. Please reconsider having another option and do the homework, do not make the same mistake I did.
