Skin cancer is easy to avoid and detect, but someone dies from the disease every 54 minutes because people forget to regularly check their skin. Using Facebook’s “memories” feature, Euromelanoma initiated a campaign in which users could pick up a Skin Memories measurement sticker from their local pharmacy, apply it to a mole, take a photo of it, and share it on Facebook. Facebook’s automatic sharing of posted memories would then remind users to check the mole for signs of skin cancer once a year.
