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.

Previous studies have shown that curcumin can decrease sunlight-induced inflammation, damage to human skin cells and the expression of sun-induced collagen destroying matrix metalloproteinases (MMPs).

Curcumin Nanoparticles May Be Viable Adjuvant for Sunscreen

Mice pretreated with curcumin nanoparticles had less erythema and inflammation, decreased apoptosis and less p53 expression following exposure to UVB than those in the control group.

Research Suggests a Need for After-sun Sunscreen

According to a report from Yale, the damage caused by UV radiation continues hours after the sun exposure occurred. In the described study, melanocytes generated CPDs both immediately and hours after UV exposure had ended. This may suggest the need for “evening-after” sunscreen, designed to block energy-transfer.

The Quest for Avobenzone Stabilizers and Sunscreen Photostability

Butyl methoxydibenzoyl methane (BMDBM) is well-known as an effective UVA filter when it is stabilized. Here, the authors measure the efficiency of ten commercially available products that are reported to stabilize BMDBM. The most effective product found was octocrylene that, being a UVB filter, also contributed to the SPF.
