Lancôme, the brand created by Armand Petitjean, is celebrating 75 years of giving women the tools to look chic. Starting out with just five fragrances back in 1935, Lancôme has now established itself as a world leader, a visionary, in skincare, makeup and fragrance. In recent years the brand has introduced to us life-changing products such as Hypnôse Mascara (its number one selling mascara) and the 10-years-in-the-making Génifique Youth Activator serum. The success of the products is as much down to who sells them to us, as it is to their effectiveness. Lancôme has been particular about its ambassadors, selecting only those who truly embody the Lancôme spirit. At the moment, that line-up includes Julia Roberts (pictured at the Valentine's Day premiere), Kate Winslet, Daria Werbowy and Elettra Rossellini Wiedemann. All bring something different to the table, but which is your favourite?
