I received 0.5 ml of filler 3x (Feb 2022, June 2022, May 2023). Over the past year, I have noticed a discolored area on my top lip, particularly when I smile. This only became very noticeable to me in mid to late 2023, but when I go back and look at pictures from earlier, I do see it earlier too. It seems like it has become darker over time and is now prominent in any photo I smile in. My provider said she has no idea what it is. Could it be a broken blood vessel, and would dissolving help?
