Please note that the above only applies to those who buy the new Kiehl's Midnight Recovery Concentrate ($95). I can't make any promises for those who are silly and don't. See this little wonder saved my ass on more than one occasion at Fashion Week. Because despite running from show to show, doing approximately 832 interviews and writing up beauty how-to after beauty how-to, looking tired is not the done thing. Gnarly, dull skin is one trend that will never take off. This serum replicates the skin's natural lipids to boost repair and regeneration through the night. If the science is too much for you, here's what you need to know, plain and simple: you look less tired, your skin is soft, hydrated and worry lines disappear come morning. The lavender also made me sleep better. Love, love, 1,000 times LOVE. Sounds good, huh?
