Redness around my upper lip 4 months after lip filler! What is this? (Photo)

Dear danet21,
I understand your concern. However, without a proper assessment, it would be difficult to determine what went wrong. It is best that you visit your plastic surgeon for further assessment or ask for a second opinion. Only after a thorough examination, you can get proper recommendations and advice.

Bruising, swelling, sometimes discoloration, lumps, and bumps are normal side effects assuming proper injection. They should be gone in a matter of days. In general, if it continues to feel uncomfortable up to this time, consult your doctor to get a complete assessment or have the filler dissolved if filler is still left.
