A childhood belief about around the house

When I was little would buy Tide detergent and on the back of the box there was a woman and her daughter doing the laundry together, but for some reason they didn't have a face. There was only an empty circle where the face should be. So, one day I asked my sister, who is nine years older than me, why they were faceless. And being the tormentor she always was, she told me they got the detergent on them and it made their faces fall off. Needless to say the began chasing me with the box and threatened to wash my face off, and she did so on a regular basis.
