We have been making our own moisturizer for the purpose of preventing and treating diaper rash, eczema, chapped lips, hands and feet. It works great. It is easy to do. All you need is jojoba oil, bee wax, and a pot. Heat the jojoba, then put the bee wax in the pot until the wax melted, then pour it into a glass jar and let it cool, and you are done. We saved the used baby food jar for this purpose. No need for high temperature, just enough heat to melt the wax. The ratio depends on how hard/soft you would like the moisturizer be. You only need a little bit of bee wax to make the jojoba oil into solid phase. Test a few time, and then you will find the right ratio you need. Now you have a facial/body moisturizer, lip conditioner, anti-eczema and anti-diaper rash moisturizer, all in one.
As shown in the left photo, I often use 15-18 gram of bee wax for a bottle of 4 fl. oz jojoba oil (118 ml). And it will fill up a big baby food jar （6 oz）. You can also choose other base oil, like argan oil, avocado oil, grapeseed oil etc. We tried sunflower seed oil. It worked fine, but if you cannot finish it in time, it would smell like stale sunflower seed. Not very pleasant.
