What is SPF? 

SPF stands for Sun Protection Factor, in other words, the sunscreen's level of protection against UV rays (these cause sunburns, skin damage and may lead to skin cancer). 

 

The SPF protection time is calculated using the next equation: 

Minutes an average person would sunburn without sun protection x SPF
