Strange dot on lip. Can a lip filler cause any trauma to a vein or vessel?(Photo)

Hello, I'm considering getting lip filler as I would like to add more volume and shape. I am however worrried about a small dot that I have which I noticed when I got pregnant. The dot became more blue/purple during my pregnancy (I'm guessing because blood vessels dilate) I've previously had lip filler in the past (about 10yrs ago) and wondering whether this has caused trauma to a vein or vessel? Please share your expert advice. Thank you!
