As one of your body’s most sensitive parts, your skin demands special care and attention from morning to night – cue Estée Lauder’s Advanced Night Repair Serum. Offering an impressive 72 hours of moisture, this cult classic has been a beloved skincare essential since 1982, and so has one of its key ingredients: hyaluronic acid. Fundamental for any hydrating routine, the much-talked-about sodium hyaluronate leaves your visage beautifully soft, while vitamin E and tripeptide-32 help to protect and renew it.
