So I have these indents on both my butt cheeks that stand out like a light reflector in the dark when I walk or run. I have never had butt injections or any type of surgery done to my butt and I'm currently a rhythmic gymnast (I put in at least 10h a week). I'm 99lbs and 5ft 6 but I eat healthy. What are these dimples/indents!? How do I get rid of them!?
