Spending a lot of time outside at my job had prompted me to collect some natural sun protection oils. Carrot seed essential oil has a high SPF as does rosehip oil. I simply added these together using the rosehip oil as a carrier oil. I was in a rush. Later I am going to make a lotion with these non-nano zinc oxide, beeswax, Shea butter, and coconut oil. We shall see how that turns out. I want a solid enough consistency to use it in a roll on stick.
