The Irish Cancer Society has been inundated with donations in the last 48 hours thanks to the 'No makeup selfie' trend going viral.
Thousands of women around the country shared a selfie of themselves wearing no makeup on Facebook and Twitter in support of the fundraising efforts.
Even men got in on the craze - by posting selfies of themselves wearing makeup.
The Irish Cancer society has seen one of its biggest ever surges in donations in the last 48 hours - with provisional figures now indicating almost €500,000 has been raised in the last two days alone.
A spokesperson for the Irish Cancer Society said: “The #NoMakeUpSelfie craze sweeping social media has grown spontaneously as a viral movement and is not directly related to the Irish Cancer Society.
"We are however, very grateful for any donations from the general public, including those coming from this source, as we rely on these donations to deliver our vital services, including our free night nursing service, our volunteer driving service Care to Drive, our free cancer information services and to fund cancer research."
Cancer charities in the UK revealed today that they had raised over £3m in the last 48 hours.
The craze was started in response to the harmful Neknominations craze which resulted in the deaths of several young men last month.
'#nomakeupselfie' is currently the number one Twitter trend in Ireland as hundreds of photos continue to be posted every hour.
Independent.ie are supporting the trend and you can have your #nomakeupselfie featured on the site by emailing email@example.com.
