Restoring balance and filling in hollow ares - Mini BBL or another procedure? (Photos)

Hello doctors, I've attached several photos and would appreciate your professional opinion. I'm trying to understand whether my butt actually has ptosis (sagging), or if the issue is simply a lack of upper and side pole fullness or projection. I hv some questions: -Would you consider my butt to be sagging, or is it primarily a volume deficiency? -What procedure would you recommend to achieve a natural result? -I don't want a large or exaggerated butt. My goal is simply to restore balance, fill any hollow areas if needed, and create a subtle, natural hourglass shape that matches my body proportions. Would fat grafting alone be sufficient, or would another procedure be more appropriate? If surgery isn't necessary, would you recommend non-surgical treatments or targeted glute exercises instead? I'd really appreciate an honest, objective assessment based on the photos. Thank you for your time.
