Have you done it yet?
Women across the UK have been going barefaced for charity while men have been piling on make-up for the same reason.
Earlier this week the hashtag #nomakeupselfie began trending on Twitter and it hasn't stopped since.
The craze, which is now on Facebook as well, sees people take a picture of themselves on their cameraphone (a selfie) then donate to a cancer charity.
As the number of pictures of women grew, men got in on the act and started doing the reverse - putting on make-up.
While there is no official charity for the movement, Cancer Research UK says it has had more then 800,000 text donations during the week meaning more than £1m has been raised.
