Alternative methods for sun protection factor assessments

Ultraviolet radiation is already known globally as a great villain, due to the intensity of the damage it causes to the skin, which makes the evaluation of photoprotection offered by products available on the market an extremely critical point, especially regarding the protection against UVB radiation, the main cause of sun burn, and UVA radiation, mainly responsible for photoaging.

Just as it is important, photoprotection is still the subject of much discussion, because we still observe a great variability of results within one single study and among different laboratories. 

In addition, many people do not know the real meaning of sun protection factors (SPF) and UVA protection factor (PF-UVA), besides not knowing how to identify the adequate level of protection for their own skin. For example, does a product that presents SPF 60 protect more significantly than a product with SPF 30? 

The correct answer would perhaps be: it depends on the point of view! A product with SPF 30 blocks around 96% of the ultraviolet radiation, but for a product with SPF 60, the percentage of blocking is of 98%, only 2% of difference in percentage of protected radiation in relation to the SPF 30.
