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.

New Sunscreen Allows Body to Produce Vitamin D
Researchers discovered altering ingredients in sunscreens allows the body to produce vitamin D, which led to a new sunscreen development called Solar D.

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.

Patent Pick: L'Oréal Steps Up the Sunscreen Game
Pop Quiz: What does it take to achieve a high SPF, high UV-A rated sunscreen within the U.S. FDA's sunscreen filter constraints? This isn't a game; it's the focus of a new patent application from L'Oréal. Read on to learn more.

Sunscreens and UV Exposure: A Q&A with Vincent Hubiche
Gattefossé SAS' Vincent Hubiche shared insight on how consumers need to be better informed with the amount of sunscreen they wear and the climate’s influence on sunscreen application.

Quantifying Benzophenone-3 and Octyl Methoxycinnamate in Sunscreen Emulsions
The authors have validated a high performance liquid chromatographic (HPLC) method for the quantitative determination of benzophenone- 3 and octyl methoxycinnamate present in sunscreen emulsions.

Research Reviews Non-penetrating Sunscreen Vehicles, Looks to Jojoba
Several "carriers for the future" were highlighted, such as lipid carriers, cyclodextrin derivatives, encapsulation approaches and non-penetrating sunscreens incorporating UV filters and jojoba oil conjugates.

Safety Alert: Sunscreen 'Doping' and Foam Formats Raise Red Flags
Recent regulatory attention highlights both hidden sunscreen actives in cosmetic products, and the legal gray zone of mousse-format sunscreens — prompting calls for clearer labeling and format approval.

Future Testing, Safety and Formulating Headline the Sunscreen Symposium
"I am convinced the earth-shattering event [in sunscreens] will eventually become the greater awareness for the big difference between SPFindoor and SPFoutdoor," writes Uli Osterwalder, regarding new findings at this year's Sunscreen Symposium.

TDF Blu Voile Sunscreen Found to Protect Against Blue Light
The skin-protecting efficacy against the effects of blue light irradiation was analyzed, as well as the quantitative and qualitative evaluation of protein carbonylation in human skin explants.

Wet Skin Factor for Sunscreens: An In vitro Method, Part II
Sunscreens designed for application to wet skin are popular in part due to convenience, skipping the drying step completely. In relation, these authors propose a new in vitro test to compare the wet skin factor of sun care products. Here, 20 products were tested and compared according to several conditions in order to define the best parameters for the method.

Photostability Test for Additional Sunscreen Claims, Part III: New Claim
Proposed here is an in vitro method, based on UV transmission measurements at two irradiation doses, to test and rank sunscreens based on their photostabilities. This approach was used to assess some 107 sunscreens and shows how, by strictly controlling key parameters, comparisons between the photostabilities of products can be made, with potential for new label claims.

Improving the UV Exposure of Sunscreen During In vitro Testing
In any sun protection evaluation method, an irradiation step is required to determine the photostability of the UV filters in a product. The aim of this study was to identify key parameters involved to improve this UV exposure. Here, the authors consider temperature at the substrate surface, air flow influence and beam uniformity during UV exposition.
