Facebook’s Vice President for EMEA, Nicola Mendelsohn, has teamed up with Rankin to mark the launch of her new charity, the Follicular Lymphoma Foundation, releasing a campaign starring singer Katherine Jenkins, actress Tracey Ullman and magician Julius Dein, sporting purple veins on their faces and necks, mimicking the dye that's used to reveal the condition.

Mendelsohn, who was diagnosed with the blood cancer in 2016, posted on Instagram 'Follicular Lymphoma is a lonely disease, invisible to most with many patients, like me, looking well between treatments. This was the inspiration for the advertising campaign, shot by the incredible @rankinarchive, highlighting the lymphatic system and making the invisible, visible to all. #CureFL'.
