If you've read any of my other reviews you would know that I am HUGE on SPF. And as weird as it sounds, there are four body parts that I slather with SPF 30+ multiple times a day; my face, my décolletage/upper chest, the backs of my hands and my lips. However, I felt that there were limited options for lip SPF protection and often found myself reapplying chapstick all day. However, with the Supergoop! Fusion Lip Balm SPF 30+ in Acai, I find that after applying once it "soaks into" my lips making them soft and keeping them protected for at least a few hours. Also, I can apply the Fusion Lip Balm and (once it has soaked in) I can layer color over it. I plan to buy some for both my mother and my sister as they are outside in the hot sun a lot (my mom rides with my dad in motorcycle rides and my sister is stationed in Texas). Thanks again Supergoop! for another great product!
