This non-toxic UV sensor is suited to olive and light brown skin types (Fitzpatrick skin types III & IV). It alerts you when you are approaching your daily maximum UV exposure limit through a colour change.
The stylish packaging holds 30 sensors which is enough for a month in the sun. The sensors are beautifully presented, tying innovative form to function.
To use, simply apply the sensor to the back of your hand before you go outside. Follow normal sun safe practices and when you see a running person appear from the flames and turn dusty pink/brown it's time for you to get out of the sun.
