The move sees Clearasil join other BHI brands, such as Nurofen and Strepsils, being handled by McCann's.
Paul Stoneham, managing director of BHI, said: "This decision removes complexity and allows us to accelerate the brand innovation. Grey has been a strong partner helping us to restore Clearasil to growth as we integrated the brand into BHI after last year's acquisition. We are confident that McCann will build on this work based on its strong leadership of the Nurofen and Strepsils brand advertising."
BHI is understood to have invested 拢50m in a drive to reinvent the brand following its acquisition from Procter & Gamble, which was completed last year.
BHI has been working on positioning Clearsil as a teen brand with product extensions such as pore purifying wipes, instant effects sticks and overnight defence gel.
One of Clearasil's most recent global ad campaigns through Grey showed a teenage boy falling off his skateboard in front of a group of teenage girls, with the strapline "Clearasil can't help you with some embarrassments, but it can help tackle the three main causes of spots".
