Lip filler lump still there after 4 months, can it be harmful it I didn't get it dissolved? (Photo)

If it is not bothering you cosmetically, there is absolutely no need to get the filler dissolved. Versa is a hyaluronic acid filler and will dissolve on its own over the next few months. One thing to note about your case. You said you had 0.5ml and then went back and had another 0.5ml. Versa comes in 1.2ml syringes. I would highly advise against saving left over filler and using it later because if it gets contaminated, you can get a biofilm infection in which case the lump may never go away and may need to be removed surgically.

Hi @Nurse_Jess_RN. If you are not bothered by the lump, I recommend leaving it alone. Best of luck, Dr. Nima!
