Is the injectible Restylane manufactured in countries like China , Japan and elsewhere safe? What risks could occur from poor quality product?
Don't do it!
Injectables manufactured abroad may be safe to use in their home countries, but they are illegal to use in the USA. It is also not too smart because you don't know what you are really getting and there have been plenty of reports of counterfeit products and disastrous side effects. You are, after all, injecting it into your body and you need to be sure that what is going in there is completely safe. Risks include infection resulting in terrible scarring as well as potential paralysis and even death (from fake Botox).
