How to Make Your Own Homemade Sunscreen

Homemade Sunscreen
Three reasons you should make your own:- Control your ingredients: zinc oxide offers the best sun protection with a low hazard rating (per EWG). You can create a high or low SPF when you make it yourself.
- Four ingredients and 30 minutes is all you need.
- No need to worry about expired sunscreen in the cupboard. Make fresh sunscreen that lasts all summer long (plan for a year shelf life).
Instructions: Melt ½ oz beeswax, 2 oz shea butter, and 2 oz coconut oil using the double boiler method (Pyrex or glass container with ingredients, sitting in a pot of boiling water until mixture is melted).
Remove from heat. Add 1 oz (2 TBS) zinc oxide to melted mixture and using a stick blender, blend until all zinc oxide is well-blended. Pour into a glass or plastic container. Sunscreen is ready when solidified.
Important: clean your equipment while it's still hot. Immediately wipe everything with paper towels to get rid of the residue as much as possible. Then wash in hot, soapy water with a scrub brush.
This is approximately 30 spf – I wouldn’t add more zinc oxide than the recipe calls for unless you can handle the extra “whiteness” which might be difficult to rub into the skin. Use less zinc oxide for a lower spf.
