What Causes Signs Of Atrophy On Face Post Cortisone Injections?

Hi, I have had 3 cortisone injections in my lower facial cheek area. Trying to shrink a knot of scar tissue from a procedure gone awry 15 years ago. (facial liposuction that over time, as more fat was put in because too much was removed - it had hardened and isn t smooth like the other side.) The area is small but puffy looking and awful in photographs. My skin has just started to show signs of atrophy the past few days. But not in the area injected. A little higher up. I will not have any more injections. (they were done by a dermatologist) My question is: will this right itself? Is this permanent damage or can my skin repair itself over time? I m 46 (female) and have always had very good skin. It is fairly minor still, but there are definate depressions, dents, if you will. What do you think? Thank you!
