I'm a little nervous. I'm headed to a seriously sunny place right when I'm in a non sun mood. How will I stay protected when there isn't so much as a cloud in the sky? Layering. Sunscreen first then an SPF Powder over it. I've been doing this for a while but my powders only had SPF 15 in them... Colorscience has SPF 50!!! I'm sooo getting this.
