Seeing no results from Sculptra and Radiesse for hip dips - do these products just not work on some people?

Hi there! So I first got radiesse June 2021. I’ve had 25 vials in total. I started sculptra in October 2021 and have had 16 vials in total with my last 6 injected in april 2022. I’ve seen little to no results AT ALL. My question is- do these products just not work on some people? Is there any way I can get my money back due to the product not working on me? I feel like I’ve wasted thousands of dollars for no reason. Also, I eat a plant based diet and wonder if that would affect this somehow?
