What are the capacities of oatmeal, lemon juice, egg , and honey as a beauty product?

This is for our investigatory project. The ingridients are of course, those who are mentioned above. My problem is that, what will I write in the abstract, in the introduction, and in the hypothesis.What are the capacities of oatmeal, lemon juice, egg , and honey as a beauty product?
The Oatmeal would be used as the facial/skin scrub. The Lemon Juice would be an exfoliate. Egg would be for Protein/food for the skin and the Honey would be as a binder and possibly as a product to keep moisture in the skin.
