Friends star Courteney Cox has joined forces with Dermalogica to surprise a class of students at the skincare company's headquarters.

The American actress was tasked with giving a facial to an apprentice during the visit, and commented 'I get sent a lot of products, and I don't like to attach my name to anything unless I believe in it. I like showing the silly side of myself; I want to, in my own way, show my passion for the products'.
