OMG! I have the same thing in my left cheek!!! My Dermatologist said it was idiopathic Lipoatrophy. She hasn’t seen me for a while and it’s gotten worse! I asked for an emergency appointment and can’t get in until April 5th. Was told they treat it with Sculptra! I’m dealing with anxiety and depression which caused multiple medical issues and as a result have lost a lot of weight, and has affected my face as well!! I’m embarrassed by this and wish someone would take things more seriously! I don’t even look like myself anymore!
