Athletic body type, lean, and have worked out since I was 16 (now 30) . I have this one stubborn area under my butt that I would love to smooth out. It's not exactly cellulite but maybe it is? Considering sculptra or radiesse as 2 doctors told me could help smooth it in small doses. Any other recommendations? I know it is minimal but I do a lot of fitness photographs and it is enough to bother me! Thank you.
