Hylenex/steroid and EndyMed for prolonged post-lower blepharoplasty swelling - is it worth the risks? (photos)

3 months post lower bleph, & still visibly swollen under one eye. The doctor -- a highly rated oculoplastic surgeon – is recommending a steroid/hylenex injection to the area to improve swelling, and a series of RF o tighten skin. I'm very nervous about hylenex as so many people report here that it's left them hollow, with less natural HA, and there's a lot of negative reviews of RF for diminishing facial fat. I’m already thin and don’t want to lose volume.
