Is it only juverderm that causes the tyndall/blue effect if administered superficially in the tear trough?
Tyndall effect is generally caused from placing filler too superficially or also from layering too much filler. A visual of this may be when you look at ocean water and it looks dark blue in deeper water but clear in shallow water. This is a reflection of the light. It can happen with different filler brands, not just Juvederm.
