Smartsun is a UV dosimeter that measures the total exposure of UVA and UVB radiation during the day. This is seen through a color change, which turns orange when you need to reapplied, and pink for when you should go inside. The products change color through a chemical reaction that is regulated by UV radiation; the more intense UV radiation, the faster the chemical reaction will go and the product will change color.
According to the Fitzpatrick scale there are six skin types. Smartsun products are specially designed for skin types 1 and 2. For more information on specific skin types, see “UV radiation”.
We recommend that you contact your local dermatologist for more detailed information on different skin types.
