A cosmetically elegant, truly sheer, thin, and matte sunblock. Great for wearing under makeup. Stays matte all day, and doesn't feel heavy or greasy after a couple hours like my Dry-Touch Neutrogena spf 55. Looks like good UVA protection in a stable formula: Avobenzone (3.0%), Homosalate (10.00%), Octisalate (5.00%), Octocrylene (2.40%), Oxybenzone (4.00%). However, after wearing this a few times, I got some odd raised red bumps and irritated patches on my cheeks and forehead. Turns out this has the ingredient Methylisothiazolinone, which is a known irritant (possibly also a neurotoxin) that shouldn't be in a leave-on skin product. Tossed it. It's a shame, because it was a great sunscreen otherwise.
