Intralesional saline injections have been used successfully for treating skin atrophy due to the use of intralesional steroids, such as intralesional triamcinolone. They are believed to work by helping to dissolve and dilute crystals of steroid that may be persist at the injection site and which may be contributing to the persistence of the skin depression. I personally have used saline for this purpose with good success. As to hyaluronidase, while there is much controversy over whether hyaluronidase used to dissolve unwanted injected hyaluronic acid fillers can cause atrophy in native hyaluronic acid, I have personally encountered this and in fact sometimes use hyaluronidase as an adjunct when shrinking unwanted tissue, such as for double chins and I have used salt injections on occasion to treat individuals who have been overtreated or improperly treated elsewhere with hyaluronic acid fillers and subsequently experienced atrophy due to the hyaluronidase. It is a simple technique worth trying and gratifying when successful. However, many individuals will require re-filling with a hyaluronic acid filler to achieve optimal correction. Make sure that you are consulting with a board certified aesthetic physician with experience and expertise. Best of luck. .
