SPF in vivo veritas

SUNCERT Tool
 

The Challenge

When using a sunscreen product by the consumer, the sun protection actually provided by the product can be mitigated if the application is poorly controlled and dosed or if the product itself has a spreading variability. It is therefore difficult to quantify the final SPF that the consumer could potentially have.

The Solution

Based on the claimed SPF, variability of in vitro SPF and two statistical approaches [1-2], this tool helps you estimate the sun protection that the consumer could achieve by using this solar product.
