Is 70 units of hyaluronidase too much to dissolve Restylane?

There are no certain protocols about using hyaluronidase. Where to inject, depth, volume and density of the filler are also important for injecting hyaluronidase. Brand name of the hyaluronidase also changes amount of units. In my experience, it doesn't affect skin tissues but only hyaluronic fillers. Keep in touch with your esthetic doctor.
Try to find a doctor who understands your needs and whose esthetic vision fits yours.
Most important, try to find one esthetic doctor who can use filler like sculptress use clay.

Typically, I recommend 1 vial of Hyelnex per mL of hyaluronic acid based filler. Certain HA fillers like Voluma are harder to dissolve then others and may require more than one treatment session.
