FAQ

1Why should I use SunFly UV Exposure Stamps and Sunscreens?
To protect you and your family from the harmful effects of UV radiation. Like a canary in a coal mine, SunFly UV Indicator Stamps will warn you when your sunscreen is no longer providing optimal protection. Did you know that 99% of skin cancer and up to 90% of all the age-related changes in your skin are due to overexposure to UV rays? Simply put—we want to keep you and your loved ones healthy and looking youthful by using our products!
2Why can’t I just follow the directions on my tube of sunscreen?
Studies show that people don’t put on enough sunscreen to begin with, or reapply often enough to achieve optimal protection. Furthermore, the directions on your tube of sunscreen are generic and don’t take into account real-world variables such as the intensity of the sun, how much you have been swimming or sweating, or even how much sunscreen you applied in the first place. By detecting UV radiation at skin level, SunFly UV Exposure Stamps will tell you whether you’ve put on enough sunscreen to begin with, and when to reapply, based entirely on real-world conditions.
3Are SunFly products safe?
Absolutely. Safety and efficacy are part of our mission statement here at SunFly. We strive to use only the safest ingredients in SunFly’s inks and sunscreens. In fact, the ingredients in our UV indicator inks have an average safety rating between 1-2 (scale 1-10) in EWG’s Skin Deep Database and our sunscreens will have an EWG rating of 1, their highest safety rating possible.
4Will SunFly UV Exposure Stamps work with any sunscreen?
Yes
5How long will a UV Exposure Stamp last?
We are engineering our stamps to last 15 hours, so a single stamp will reversibly change color through multiple reapplications of sunscreen. Our stamps are waterproof, sweat-proof, resistant to both chlorine and salt, and of course, sunscreen-proof! The stamp will eventually slough off on its own, or you can scrub it off with a little soap and water.
