Launching online on 19 July, Guerlain Abeille Royale Advanced Youth Watery Oil (£73) is more than in just a ridiculously pretty package. The serum contains some innovative technology, including a new blend of honeys that, when combined, help speed up the skin's natural self-repair mechanisms. All sustainably and ethically sourced, the blend includes black bee honey from the French island of Ouessant, as well as honey from Corsica in France, Ikaria in Greece, Åland in Finland, and royal jelly, which is a milky secretion produced by worker honeybee. And because honey and oil are actually not compatible, Guerlain also to create a new unique type of formula that is rich and decadent like an oil, but as light and refreshing as water.
