What can I do for lump under eye just above cheek after tear trough filler? (photo)

If you're unhappy with your final results, you can have it reversed with hyaluronidase and try a different technique next time. See an expert. Best, Dr. Emer

I do not see preinjection photos, but your after photos may show overcorrection, or injection of too much filler. If this is an HA filler, hyaluronidase injections may be considered to dissolve the product, depending on your examination. In general, it may not be a good idea treating overcorrection with more filler. Hope this helps. If in doubt, consult with a reputable cosmetic dermatologist or facial plastic surgeon. Dr Joseph
