Coconut oil is comedigenic (sp?), meaning it will clog pores. So, if your skin is sensitive to it, like mine, I'd advise against that one, for the face. I do, however use it in my homemade body soaps and shampoo, with great results.
The egg whites can work well, but they're a temporary lift, and if not rinsed well, will leave a shiny finish on your skin that can crack, and add years to your look, until it's washed off. I've found a light swipe across my face with the cut portion of a cucumber does the same job, without the cracking, shiny finish.
Turmeric or strawberries are supposed to whiten teeth, too. I love edible beauty & hygiene products!
