Dent Above Upper Lip After Juvederm? (photo)

I'm almost 4 weeks post one syringe Juvederm in my upper and bottom lip. I wanted a subtle plump. So far, I'm very happy with the results apart from some asymmetry with the upper lip. I can only see the asymmetry when my lips are relaxed, not smiling. My smile is not asymmetric. Also, I have a strange "dent" on one side,above the lip. What is that dent and will it go away? It's soft to the touch, no hardness or lump.
