UM's responsibilities include communications and media planning, media buying and execution, as well as digital and social media strategy.
UM was named to the account following a competitive tender. According to insiders, the strength of the UM team, its innovative ideas and unique systems, especially C.A.T. and Matrix, were driving factors in the recent win.
Chris Skinner, UM managing director, said the agency is delighted to "work with such fabulous brands as Laneige and Sulwhasoo, and moreover, to collaborate with a client that is as passionate about innovation as we are."
"The utilisation of our Channel Allocation Tool (C.A.T.), which has over 80 contact points, was pivotal to our success," he added.
