Special edition sun-activated UV stickers have been created and produced by Sunburn Alert^® featuring characters from Disney Junior hit TV show Vampirina, after research finds that nearly half of parents in the UK are unsure how often to apply sunscreen to their children. The patented colour-changing technology will see the sticker change from white to blue when it's time to reapply sunscreen. A limited number of complimentary packs of stickers will be available in selected airports, motorway service areas, supermarkets and shopping centres across the UK only.
