Using a double boiler (or a small pan over very low heat), melt your coconut oil, sesame or jojoba oil, beeswax and shea butter together. The beeswax will be the last to melt.

When the beeswax is melted, remove the mixture from the heat and let cool to room temperature. If you are using Zinc Oxide, whisk it in a this point, being careful not to create a lot of dust. If there are some lumps that's ok, they will break up when you whip the butter in the next step.

Move the mixture to the fridge for 5-10 minutes. You want it to start to set but still be soft enough to whip.

Take the mixture out of the fridge and using a stand mixer or hand mixer, start to whip it. Drizzle in the red raspberry seed oil, carrot seed oil (if using) and any essential oils of your choice. Continue whipping until the mixture is light and fluffy.

Use as you would any regular sunscreen. Application rates will depend on your activity and exposure to water. Store in a glass container in the fridge between uses.
