Enhancing Sunscreen Efficacy for Realistic Application

The ability of a sunscreen to protect the skin from erythema is expressed on product labels as the sunburn protection factor (SPF)—i.e., the ratio of the minimum erythema dose (MED) with sunscreen to the MED without protection. Yet in reality, consumers do not apply the same mass/cm2 as is utilized in SPF testing, so maximal protection is not achieved.

Adapting Spf Testing Methods For Mineral Sunscreen Density

Adapting SPF Testing Methods for Mineral Sunscreen Density

A sunscreen layer’s thickness is critical to its SPF. However, current regulations specify a mass application rate for testing, rather than a volumetric application rate. This significantly underrates the SPF values of mineral sunscreens due to their higher densities since, compared with their relative organic counterparts, thinner films are being tested, as will be shown here.
