Can wrong technique injecting Juvederm cause scarring, damage? (photo)

It is unlikely that your injections caused tissue damage or scarring. I recommend getting a formal evaluation to determine cause. If this is still filler, it can be reversed again with Hyaluronidase. It may take a series of treatments. If this is swelling, 5fu injections may help. I recommend using Belotero for under eyes with cannulas to limit complications and swelling. See an expert.

Thank you for sharing your question and photograph and I am sorry to hear of your swelling and scarring issues.  In general it would be difficult to cause tissue damage or scarring as a result of dermal filler injections.  The needles/cannulas used are quite small and the depth of placement is fairly superficial.  I think what would be more common is inappropriate placement of the filler during treatment.  I would review these issues with your injector in order to have the best information supplied. 

The problem is that these are not good products for the eye area. They can lead to chronic edema. Restylane is a much better choice. Sometimes they are hard to dissolve with hyaluronidase. Make sure that Hylenex is used. Compounded hyaluronidase is very weak. Also make sure that the appropriate dosing is used. At least 100 units for these stubborn lesions. I don't believe scar tissue is formed from the injection. Sometimes a collagen response occurs from the filler and sometimes an inflammatory response. Injecting FU can settle these resistance areas down, 25 mg. It takes a while for the swelling from this to settle down.
