I'm sorry to hear about those awful experiences... I got 2ml of Voluma in my chin and 18 months later, it's still there The bad reviews I've read are all about the Tear trough, a very risky region but what about others? It's seems like hyaluronidase has caused damages either by having repeated session or because of a large amount By having a tiny amount like 20units in my chin, do you think that it's possible to avoid that risk?
