Barrymore's review: "I break out from almost every sunblock. So I'm like, 'Do i want acne or Brown pigmentation?' It's always been a crappy toss up. Then I found this. It's a lightweight sunscreen with a tiny bit of tint and a good number SPF. I have been long time fan of this line. They have several options, and all are amazing!!!!!"
