Maxwell House coffee’s slogan, good until the last drop, should moonlight as the catchphrase for Clarins Blue Orchid Face Treatment Oil. Mix-mastered from 100 percent pure plant extracts: rosewood, patchouli and blue orchid; a healthy helping of hazelnut oil; and nary a preservative, this deeply moisturizing serum is as good as it gets. And the French beauty brand’s highly skilled research and development team knows it: every Clarins product undergoes a lengthy process from botanical extractions and formulation to laboratory testing to the store’s shelves. And while we appreciate their dedication to our skin, what we really love is how this treatment oil revitalizes and restores radiance to our dehydrated (and aging) face. We also like to think that it diminishes our fine lines, too, and that makes this tiny glass bottle’s price tag a worthy splurge.
