Downside is that it has insignificant white residue. Good sides: nice under foundation and blendable.
I am very picky about my sunscreens, but this one really impressed me! It's the first non-cleansing item from Is Clinical that I have tried. (I already use their non-foaming face wash, and I love it.) It has a really smooth, almost whipped texture. However, it isn't the least bit heavy or greasy. It soaks in right away and doesn't leave a white cast - and that's rare for physical sunscreen! As an added bonus, it's super hydrating and makes my skin glow. It works well under both liquid and powder makeup. I learned recently that physical sunscreens need to be removed with either an oil cleanser or a micellar water (as they are not water soluble, but oil-soluble) but with the right cleansing balm it isn't difficult to do. It hasn't broken me out yet, and I've been using it for a couple of weeks. The packaging is very sleek, as is the norm for this brand. The only thing I would change about this product is that it is slightly tacky when first applied. However, this is a small flaw, and it dries down to a matte finish in a matter of minutes. I recommend it!
