This is by far my holy grail sunscreen out of the countless I've tried in the past (and believe me, since moving to sunny california I have been on an endless hunt for the perfect high spf yet still sheer sunscreen). Starting out with my least favorite bit about this: the price tag. It's a name brand so you'll have to fork out some extra dough, but the benefits far outweight the cost. The problem with most physical sunscreen is, like my past beloved Shiseido, is that they usually contain titanium dioxide, which leave a pale white mask on my face that wouldn't blend in with my skin no matter how much I rub. Kiehls is a chemical sunscreen that has a super smooth formula that immediately absorbs and blends in with the rest of my moisturizer. The scent is mild and not overwhelming, another big plus since my skin is super sensitive to sunscreens yet I have not ever broken out from this. The SPF is perfect for extended stay in the sun (though I still need to reapply every couple of hours), and the tube is classic Kiehls: minimalist and sleek and ergonomically designed to easily be handled and fit into your purse. People who are afraid of burning (or tanning even!) and don't want to suffer the white mask that is prevalent in almost all physical sunscreen...get this!! I'm positive it'll be your new favorite sunscreen too.
