Can I fix lateral gluteal depressions? (photo)

Hello dear!
Thanks for the question and provided information as well.
Based on your pictures, you are a good candidate for liposuction with fat transfer, to improve your buttocks and hips, and I think you'll get very good results. 
In general, you need to be physically healthy and at a stable weight, have realistic expectations, be a non-smoker and your BMI needs to be 30 or less.
l recommend you to make an appointment with a board certified plastic surgeon to talk about your goals and anything you need to know.
Good luck :)

That is very possible!Filling in the lateral hollow is one of the best things about the Brazilian Butt Lift procedure.  Most of my patients want a fuller, rounder buttocks and an hourglass body figure.  DiscoverTheBeauty.com  The BBL procedure can provide both.  It includes removing unwanted fat from around your waistline and transferring it to your buttocks.  When done correctly, this is always successful!   I have never had a patient lose their transplanted fat.
