SPF or acidopholis

We've been doing a lot of work in our yard over the last few weeks. Before we go outside we put on suncream. Today Michael put his sunscreen on in the kitchen while we were talking about mulch and the yard and things. I noticed Sabrina was putting some on her face and saying, "I put on my cream. My cream. I put on my cream." And I thought, "How did she get it out of the tube?" I walk over to her and realize, she had gotten plain yogurt off the counter and was rubbing it all over her face! Not sure if that gives the kind of sun protection you need!
