Each foundation formula created by Arbonne is for all skin types and has some form of sunscreen protection. The Colour Wand and Defiance Makeup both have SPF 8 and the Mineral Powder has SPF 15.
According to the American Cancer Society, having a sunscreen in the foundation is not the best option. You should be using a product (moisturizer with SPF or sunscreen) prior to applying foundation. So don't make that a selling point for purchasing foundation. And remember to always wear a sunscreen prior to applying foundation, even if your foundation has a sunscreen in it.
I was able to try all three formulas; the following is my opinion of each one.
Because everyone has a different result in mind for foundation, Arbonne is a good choice to give you those options.
