Reapplication is key, people! If you're out and about in the sun, you should reapply some type of sunscreen every two hours. While this product goes under your skin, Supergoop! has sprays that are great to use after you've applied your makeup, but more to come on that (in like one second, it's literally the next product)!
Promising review: "This is it. This is the perfect sunscreen. Supergoop has done it. I'm calling it now that Unseen Sunscreen has just broken the final barrier of sunblock for all of us. A sunblock with strong SPF, that does NOT 1) make you pale/chalky, 2) make you super greasy/shiny, and 3) sit stickily on your skin and visibly in photos. Not only does it not do the above, which I NEVER THOUGHT POSSIBLE, it also comes with antioxidants and good stuff for the skin. It applies feeling EXACTLY like a primer, almost immediately feels invisible from the skin, gives a vague velvety blurring effect, and accepts makeup well. Thank you, Supergoop. I'm in my late 20s, and it has never been more important to remember daily sunblock. With this, I know I will." —MsFourEyes
