White patches on lips after filler - Is this normal? (photo)

I have had filler done a few times. I tried someone new today and immediately after the filler parts of my lips are white. Please tell me this is normal? It has never happened to me before and I have been reading up on vascular occlusion and I'm worrying that's what's happened. This photo is an hour after the filler. Please advise if this looks normal.
