hi , I am an aromatherapist. Beeswax is an ingredient that should be added sparingly to creams, it tends to harden quickly and it is not an easy ingredient to work with. You need to have very good ingredients to keep the beeswax balanced so it doesnt get hard in your cream. You should definitely use base oils and add some essential oils to them.
Jojoba, almond, and grapeseed oil are light and you could add your essential oils to them for body oils or face oils. Jojoba is the easiest for your skin to absorb. Grapeseed is a good antioxidant.
avocado and olive oil are very good but they are heavier. If you are interested in making a "cream" why dont you try whipping some shea butter and add your oils to this?
