There is a white triangle between my nose and lips 6 months after Perlane and 3 months after Vitrase in nasolabial fold. Advice?

The use of Perlane is meant for deep folds or lines.  Usually it is not used above your lip.  You said your nasolabial folds were treated.  The white area may be the result of too much product in the area or it was injected too superficially called the Tyndall Effect.  It is concerning that 6 months you had the HA and 3 months the Vitrase which is suppose to dissolve the product.  I would strongly suggest going back to the place where you had your treatment and speak to the physician.

Good luck to you.
