I’m not sure if there is a definitive answer to this sadly. Mine stopped. I saw a dermatologist privately who listed connective tissue disease as one of her specialities not long after I became aware of the subcutaneous fat loss. She requested an autoimmune blood test which came back very weak positive, although this result can occur in those without any autoimmune issues. She believed that if this was a reaction to coming off finasteride then I may have taken a one off “hit” and that it was probably not continually degenerative in nature (I’m paraphrasing what she said as I can’t remember her exact words). Although this has proven to be the case for me, there do appear to be other cases where the damage appears progressive. I would discuss with a doctor if you have any concerns, although I appreciate that they are not always the most open to what has happened. Maybe if you had photographs to show them of what you were like before it might help convince them that this is real. It could be that you have become aware of the fat loss whilst you are losing it whereas I became aware of it later on? Maybe it is a process that reaches an equilibrium post-finasteride?
