Am curious to know how effective these wristbands are….
They are apparently now available in Canada.
“Smartsun UV Wristbands employ a patented technology to enable safer sun enjoyment, reducing the risk of sunburn, premature skin aging and skin cancers by indicating when you should reapply sunscreen and when you’ve had enough sun for the day.
Dermatologist designed and laboratory tested, Smartsuntechnology involves a chemical reaction set off by the suns’ rays causing the band to change colour reflecting the cumulative daily level of UVA and UVB exposure. Uniquely, Smartsun UV Wristbands account for sunscreen applied in measuring exposure to UV radiation, prompting the user to apply more sunscreen or to get out of the sun altogether at the right time.”
