Is hyaluronidase a good and safe option for me?

Hi! In March I had two syringes of Juvederm. In October I had three more, and then in November three more, totaling eight syringes in nine months, which is probably too much for a 28 year-old. Do you think the roundness is my face is the result of excessive juvederm? (My weight has not changed.) Also, is hyaluronidase safe? Im hesitant because on RealSelf over 20% of people who have used it reported irreversible facial tissue damage.
