Radiesse shelf life? What happens to product if it’s 5 yrs past the expiration date.

Thanks for writing,Self life’s are based on the long term testing and the quality of the product to that point in time. That being said, I would never consider injecting a product 5 years old. Stephen M. Davis, MD, FACS

I would not inject a product that was 5 years old.  The product thickens and the company will not guarantee an old product.
