I had 1 ml Juvederm Voluma and 1 ml Juvederm Volift midface, undereye 5 months ago. I had puffiness and went back three times to dissolve the product with Hyase. Later it turned out that swelling was due to edema that I had for like 4 months. My nasolabial fold looks more prominent then before and undereye there is a bump, scar. See photo. My question is can wrong technique cause tissue damage? What can cause the puffiness in the nasolabial fold? Is it Juvederm or damage to the tissue?
