Facebook has a feature that shows people the pictures they shared on this day, one or more years ago: Facebook Memories. Euromelanoma decided to use this feature as a tool to remind people to check their skin.

We developed a transparent sticker with a clear call to action. It asked people to put it on one of their moles, take a picture and post it on Facebook.

Exactly year later, Facebook Memories shows them the same picture mole again privately. Reminding them to check the mole again.

The sticker shows a transparent grid that allows them to measure the exact size of the mole, even on a picture. So thanks to the Skin Memories sticker combined with Facebook's wellknown feature, people can assess its evolution year by year.

The stickers were distributed in pharmacies nationwide.

Influencers shared their moles with their followers, asking them to do the same.

The campaign was launched on April 12, 2017. 100 000 skin memories stickers were distributed in pharmacies nationwide. In the week that followed,14 influencers, celebrities and the national Minister of Health posted a picture of their mole on Facebook and/or instagram. Each post was accompanied by a text encouraging readers to get their own sticker at their pharmacy and share on Facebook. After a week already, pharmacies were asking more stickers as demand was growing. Currently, Euromelanoma is looking to print more stickers, but also to roll out this campaign on a global scale.

Our message was picked up by the national media as well as the digital community, resulting in nationwide reach.

100 000 stickers were picked up at pharmacies within a week, and spread on social media. 80 percent of people posted their picture in private, making it only visible to themselves. The other 20 000 posts reached an audience of about 4 million people. Raising awareness for a facebook audience, and more importantly: generating thousands of reminders for people to check their skin.

We wanted to reach people of all ages - because skin cancer can occur at any age. Since almost never check their skin but do spend an average of more than 50 minutes a day checking their Facebook, it was clear this was the perfect medium to reach a large audience. With a clear call to action on the Skin Memories sticker, we asked people to share a picture of their mole on Facebook, using the Memories feature as a tool that reminds people of the evolution of their moles, year after year. Making the medium all the more relevant. To rapidly share our message, we got the help of celebrities, influencers, and even the Minister of Health, who used the Skin Memories sticker to share a picture of their mole on Facebook and Instagram.

Skin cancer is the easiest form of cancer to avoid. It can be seen an detected in the earliest stages. Still, after decades of awareness campaigns, a person dies of skin cancer every 54 minutes. Because people just seem to forget to check their skin.

Euromelanoma, a european skin cancer prevention organization, wanted to raise awareness, but also actually remind people when the time is right for them to check their skin.
