In a behind-the-scenes video clip from the ad campaign, the House star sits in a chair while his nails are filed by an attractive assistant.
'My name is Gerard Butler, and this is how I look before I've applied L'Oréal's skincare for men,” jokes the 52 year-old.
“I’m very flattered to have been thought a fit subject to promote the idea of beauty, I care about beauty,” he jests.
“It’s hard work. This, as you can see, is very hard work,” he says as he relaxes in his chair and lets the assistant do the work.
The Blackadder star also pokes fun at the L'Oréal tagline 'Because you’re worth it'.
“Am I worth it? That’s an interesting question to pose,” he says.
“We are all struggling with the idea that we are worth something, what are we worth? I hope I am, I hope you are, I hope we all are.”
