Small white dots on my lips after lip fillers (Photo)

I am very woried about small white dots on my lips that appeared after lip fillers. I had 0,5 ml in early and than again 0,5 ml in mid december (this was my first time getting lip fillers). And I did notice one or two whitich dots month or two latter on my upper lip but wasn't concerned about it. I got filler again in march. And now I am very concearned.
