How Do I Remove Restylane Irregularities in Lips 5 Months After Injection?

I would personally inject hyaluronidase into the concerning areas as Restylane can definitely last longer than 5 months in the lips. If the fullness does not resolve, then I would consider an injection of dilute steroid and aggressive massage. More than likely, your lip will return to it's pre-injection state. I have never seen "scarring" in the lip due to injections of Restylane, no matter what the technique is.

It is possible that you still have residual restylane in the lips, which can be causing you problem.  It is not uncommon for the product to last that long in some individuals.  If this is the case, injections of Hyaluronidase will help to dissolve the remaining Restylane.  If scar tissue is present, this may pose a more difficult dilemma.  Good Luck, Dr. Corrado
