I've had a bunch of HA done in Toronto, from two practitioners and two variants of Revanesse. I'd strongly suggest asking for Contour vs Ultra or perhaps having a consult with my preferred injector, he'll do them for free and even virtually if logistics are tricky for you.
No experience with Restylane. The Revanesse Contour is firmer than the Ultra. Also comes in a 1.2ml syringe. As for gains you'd have to ask your doctor but I'd say you'll get half an Inch if not quite a bit more from that much, especially if you're saying give or take 10ml lol.
I'll send you a PM. Can be a bit more candid there. Feel free to reply if you want details about my two experiences.
