After 1 year and a month BBL hips are gone

Hi, I had my bbl 1 year ago. Still last month each side of my hips were still feeling hard and hips looked bigger. Now, I don't feel that hardness in my hips anymore, and feel the size went down. I am not sure what happened, I lost little weight, but before even I lose weight the hips were hard and prominent and now I feel that part it's soft to the touch, not prominent anymore
