Recurrence of vascular occlusion from 6-7 months ago (36 y/o F)? (photos)

Two days ago I noticed a cluster of tiny white bumps on my lower face that looks similar to a vascular occlusion I had resolved in Feb. I have no pain, no itchiness, and no changes in my skin care routine. The only thing I can think of is I had a random bug bite to my bottom lip so I applied ice and then I woke up with this. I have not had any fillers or injections placed anywhere in my lower face since then. Is this part of that filler issue or just acne?
