Ultragen's new skincare product Stop will be sold in Selfridges and Harvey Nichols from September.
The agency will handle consumer, digital and trade communications following a three-way pitch.
It will position the product as a 'pioneer in the anti-ageing market'. It will secure independent endorsement from plastic surgeons, dermatologists as well as selling in case studies of the clinical pilot studies from Tel Aviv, Paris and London.
It is planning a series of events to drive footfall and celebrity endorsement will also feature in the campaign.
The device will be aimed primarily at women over 35 years old through women's magazines including Harpers, Vogue and Grazia.
Consumer director Christine Morgan will lead the account reporting to sales and marketing vice president Oded Rose.
