Hi Dr. Lam,
I had Juvederm to fill in tear trough areas below the eyes. The places of injection look darker at certain light angles. I was hoping this was bruising so got treated with low settings of V-beam but it didn't resolve it. I think it's called 'Tindal effect' - the filler scatters light in a certain way beneath the skin and creates that dark-circle impression.
Does such problem occur in your practice using Resty or Juvederm below the eyes?
