It's been a crazy old week in Facebook world.

Over the past 10 days, the social media site has gone into overdrive with a plethora of people inundating newsfeeds by posting make-up-free ‘selfies’ in the name of cancer. (For those unaware of what a ‘selfie’ is, it’s a photo taken of yourself, by yourself, and then uploaded on to social media sites).

When it all started, I must admit it threw me. Suddenly, girls I went to school with that I haven’t seen for over 10 years, were dominating my Facebook page in all their bare-faced glory, leaving me totally bemused and wondering what on earth was going on.

It wasn’t apparently obvious at first that by posting pictures of themselves wearing no make-up, they were actually trying to raise awareness of cancer charities and donate money to them, until some negative backlash about the true intentions behind the exercise.

Next minute, people were posting the pictures alongside a link to prove they had donated £3 to charity, with cryptic comments about the negative people.

I admit, at first I thought I was missing the point. What good posting a picture of my freshly scrubbed and gleaming face would do to help cancer was beyond me. Couldn’t we just donate and forget about the picture altogether?

But then the whole thing just spiralled. It sparked a huge internet debate. Did the selfie actually raise awareness of cancer, or just of the person posting it? Was it really about cancer or was it just narcissism veiled in philanthropy?

One friend who felt strongly about it, didn’t post a photo of her bare face which she thought had nothing to do with cancer, she instead donated, and posted a guide to the symptoms on breast cancer and how women should be checking themselves properly.

I thought that was really useful and did the same thing.

It also made me think, what about the men? They get breast cancer too, why has the exercise been so heavily focused on women who are wearing no make-up?

The backlash has been incredible. Donating appears to have turned into a bit of a pressure – if you haven’t posted a photo of yourself not wearing make-up, does that mean you aren’t doing your bit for cancer?

According to my colleague Rhiannon Bevan: “The actual argument itself is causing people to donate and not the original trend. People are almost donating in protest, by posting a photograph of the fact they’ve donated.”

But let’s look at the facts. In less than a week, £1m was raised for Cancer Research. We have to admit that’s a good thing.

Does it really matter if a few people have posted pictures for vanity reasons – as long as they donated, who cares?

I lost my own mum to cancer, so the bottom line is, anything that raises awareness and money to help get rid of such a vile disease is good in my book.

I do feel that it’s a bit sad we appear to live in a world that relies on narcissism to spread such a worthy message, but if it helps raise money, it doesn’t hurt anyone, and it saves just one life and one family from going through the hideous experience of watching a loved one go through cancer, it gets the thumbs-up from me.
