I tried making a homemade eyeshadow out of coconut butter, arrowroot powder, cocoa powder and cinnamon.
Mix together 2 tsp of cocoa powder, 1/2 tsp of arrowroot powder and 1/4 tsp of cinnamon. You can play around with the ratios to get a colour you prefer. Arrowroot makes it lighter as it’s a white powder, cocoa powder makes it dark and deeper and cinnamon gives a warmer tone.
Once you’re happy with the colour, blend the powder with a teaspoon or so of coconut oil. (You can use shea butter but I didn’t have any and I read online that coconut oil is a good substitute)
Put into a jar and store in the fridge for a bit to help set. I think it’s ok to store outside the fridge too, just not sure if it can go mouldy or not!
