With unprotected sunning and late nights out in the sultry heat, perhaps you haven't been as kind to your skin as you could have been this Summer. Let Estée Lauder's Advanced Night Repair Synchronized Recovery Complex II (£44-£65) be your answer to a rejuvenated complexion while you sleep. Can it be any easier than that? Made with hyaluronic acid, the serum leaves skin not only soft and silky, but also subtly plumped up. And a blend of antioxidants help to protect against and neutralize environmental aggressors. Apply on freshly washed skin prior to moisturizing — you'll love the fresh, astringent scent — and let this potent potion do its thing while you're off to slumberland.
