Developed with UV-Sensing technology, BEAME’s Under the Spotlight UV Detection Stickers (36 Pack) is a colour-changing patch that signals when it’s time to top up the SPF. Adhered to the skin, apply your sunscreen as usual (even over the sticker). Then, its sunlight-responding polymer will change colour from clear to purple, indicating that your SPF needs reapplying. Sweat and water-resistant, the flexible adhesive is comfortable to wear and promises to stay in place all day, even when swimming or exercising.
