Beyond expiration date?

The box was sealed, however I was unable to find an expiration date on the packaging or product. I've been told by my esthetician that the lack of a date means that the product is likely at least 2 years old. So, without any information about product stability, I'm not sure how this product will act on my skin. Just a warning to anyone else thinking of this purchase.
