SPF stands for Sun Protection Factor. SPF value refers to a product’s ability to block the sun’s UVB rays. It is measured by the amount of solar energy necessary to cause a noticeable sunburn. This means that when you use products with a high SPF, more solar exposure is required to induce sunburn than when you use a product with a low SPF.
