Age 31, what are your experiences of facial fat transfers in people with autoimmune disease?

I'm hoping to get a facial fat transfer to help restore lost volume in my face. I'm 31 and when I was in my early 20s I developed autoimmune disease (Sjogren's and psoriasis) and during a short period of time I lost a lot of volume specifically and only in my face. Can't prove it was the illnesses but it happened at the time of onset and never corrected. Curious if anyone has any experience with this procedure in autoimmune patients. The illnesses are chronic but can flare.
