How many units of Hylenex do I need to dissolve Restylane Defyne/Refyne?

It really depends on how much was used and how much of the effect you want to reverse.If you want to keep some of the effect in some areas, spot treatment is ideal. It allows you to reverse without overdoing it. It's better to do too little that too much in most cases.Be sure to explain your timeline and expectations with your surgeon.
