And now for a little game we'll call Beauty Packaging Déjà Vu. In the past two weeks or so, both Emily Ferber and Claire Knebl have accumulated quite the collection of these nice black glass bottles. Not that they're complaining—all the products are excellent, from Garrett Markenson Reverie Milk Anti-Frizz Treatment (smells like an herby bouquet and turns days-old hair into something beautiful and manageable) to May Lindstrom's The Good Stuff Radiance Oil (for the body and shimmery!). Then there's the baby versions: May's Youth Dew and MUN's No. 1 Aknari Brightening Youth Serum. We're all about diversity in the medicine cabinet, but it's sort of nice to end up with something of an inadvertent uniform. Also, the little caps are adorable—like hats for your pump tops. Form and function, people—that's what it's all about.
