White bump on my lip after lip filler?? Should I be worried? (photo)

It's difficult to tell from your picture. I recommend following up with your injector for a formal evaluation. 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

Dear aseguna,it is hard to tell for sure without an examination. I would suggest you to consult your injector. Only after a thorough examination you will get more information and recommendations.Daniel Barrett, MD, MHA, MS
