More Packaging? Is it really necessary?

I took my grandmother on a shopping trip yesterday and was tasked with looking for her face cream by Oil of Olay. She was bothered by the fact the packaging seemed different as she likes to stick to what she knows.

I was bothered by the 'new' packaging too.  To my horror, in addition to the cardboard box that surrounds the pot that contains the cream, was yet another layer of packaging, a clear plastic box.

 Why?


Please, someone tell me what possible reason there can be for adding yet another layer of packaging to a product. I had considered looking at their range, BUT, I've changed my mind.  I refuse to buy anything that is so much more package than product.
