Restylane-L used close to expiration. Is that normal?

It is perfectly safe to use Restylane within one month of the expiration date.  The product is still safe for use.  Every doctor orders product differently.  Some place a very large order which may result in having product closer to the expiration date.  

There is nothing to worry about using this product. The FDA requires companies to place expiration dates on products. In reality, they could probably be used for years after the expiration. There is no decrease in efficacy or sterility you should be concerned about.
