I had moderate old acne scars and have shown a lot of improvement as they are not too noticeable unless in certain lighting after a Morpheus series. I just want to know if the fix is permanent or not. If the scars are in dermis then when the collagen decreases with age will scars come back? Will they be the same or come back less noticeable? Will they get worse eventually and will treatments stop working or if I get a TON of laser treatments can they be permanently erased even with age?
