I received Restylane Lyft in my lips, and now I have white clusters. What are they? (photo)

I received Restylane Lyft in my lips four days ago, and yesterday, I noticed these clusters of white bumps at the injection sites. I have reached out to my injector, who says they are my glands which sometimes appear with enhancement. She said they can’t massage out, and they *might* go away once swelling completely goes down. Three weeks ago, I had 1/2 a vial injected, but after swelling, I wanted her to do more. These bumps weren’t present. I had her do another 1/2 and these spots appeared.
