The UV Card

What is the UV Card?
A simple, reusable, credit card size device that indicates the ultraviolet light intensity. Excessive levels of UV light can cause sunburn, premature aging of the skin, and skin cancer.

How does it work?
The UV Card measures the strength of UV light (in about 20 seconds), to help you determine the optimum level of sunscreen SPF to use.

Test Sunscreen
With our optional clear plastic card jacket* you may also test suncreen. Apply sunscreen over the protected indicator strip - if it works on the card, it's working on you. Also indicates when to reapply sunscreen. You'll be surprised at how much UV light exposure you receive even on cloudy days, or through windows.
