Why the FDA's 'Sunscreens in the Bloodstream' Study is Flawed

A recent study published in the Journal of the American Medical Association tested the potential systemic absorption of certain sunscreens. Results identified their presence in subjects' bloodstreams; however, as industry expert David Steinberg explains, the study is misleading and fails to consider crucial variables.

Unexpected Paths to Sunscreens

Teleportation was once science fiction. Today's it's somewhat of a reality, if you consider how Facebook Live, Facetime, Skype, etc., transport our likenesses through time and space. I sense this indirect path may be the future to sunscreens.

Research Pathways to Photostable Sunscreens

This article provides a visual depiction of pathways that UV filters undergo when exposed to solar radiation; such pathways often lead to photo-instability. A fluorescence technique is described that has led the author to identify compounds that preserve photostability in a novel manner— by quenching the UV filter’s singlet excited state.

Guiding Sunscreen Traffic Across the Globe

Sunscreens are classified and regulated differently around the world. For instance, the United States considers sunscreens as OTC products, while Canada has a two-part classification system; other places classify sunscreens as cosmetics. Labeling and registering differ worldwide as well. In some cases, labels require certain Drug Facts or safety registration numbers, among others. This article reviews these differences.

Effective Sunscreens for Everyone Under the Sun

Today, we take the effectiveness of sunscreen products for granted. As the industry knows, this performance is not simply a happy coincidence. Here, we review the steps in the sun care R&D process and consider where questions may arise.

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.

Quantifying Sunscreens and Preservatives in Cosmetic Products

The authors propose and validate an HPLC method for simultaneous quantitation of commonly used commercial sunscreen actives and preservatives in cosmetic emulsions.
