Danielle: lucky you for getting it for free. I haven’t tried any vibrating mascaras yet, I’m too scared I’d poked myself in the eye lol. But I’ve tried definicils by Lancome and that smudged a bit too.
As for the wristbands, they’re disposable and shouldn’t be reused. Here’s what the UVsunsense website says: “A partially-used band, when re-exposed to the sun, starts monitoring UV rays from the point it was at when you last took it out of the sunlight. Use only one band a day per person, and then discard it.”
