When I was the beauty editor at teen magazine CosmoGirl!, we frequently published recipes for skin and hair masks made from common kitchen ingredients like honey, avocado, yogurt and eggs. The treatments were easy to make (albeit messy) and mildly effective. The new Facial Moisturizer Kit from Ktchn Apothecary is kind of like that, but with more grownup, potent ingredients—and far less cleanup.
