Sculptra for hip dips - Would this work on me? (photo)

I have been so self conscious of my hip dips for a long time. I have tried the gym to fix them but it is not possible. I am slim so fat grafting is not an option. I also see that hip implants seem to not be done in the UK. I am now looking at my only option which is sculptra. Would this work on me? Looking at my photos it looks like I have fat above my hips but it’s actually muscle. Does anyone have any idea how much I would need? I want to fill in my hip dips and also make my hips a little wider.
