If you like to add beeswax, melt it first and let it cool down for a bit. If your shea butter appears to be fairly solid, you can melt it together with the wax (or on its own if not using wax).
Add all the other ingredients (oils, shea butter, essential oils, water & aloe vera gel or powder) to a tall measuring jug or a high-rimmed bowl.
Blend the mixture at a low speed, if your stick blender is quite powerful (600Wplus). Weaker ones (around 400W) are fine at a higher speed. Blend until a creamy lotion forms. Depending on your blender, this happens after a minute or two.
Pour your aloe vera face cream into a clean container or glass jar and put it into the fridge to set, for several hours. After that, it’s fine to sit in your cupboard, especially if you used beeswax.
