Considering more and more sun care products are claiming infrared (IR) protection, it is important to standardize the parameters by which they are evaluated. Since IR-A and IR-B are the most implicated in skin damage, a test method was developed based on these wavelengths, as described here.

Our historical beliefs as to the causes of hair breakage have been largely shaped by findings from testing approaches. More recently, an alternate mechanical testing technique, fatigue testing, has been changing our perspective on this topic.

DABBA is a synthetic peptide that mimics Waglerin-1, a toxin from the temple viper. It is shown here to reversibly inhibit muscular contraction and reduce wrinkle formation, and to induce the expression of genes that improve collagen fiber maturation. Notably, differences in anti-wrinkle effects were observed in different ethnicities.

Until now, testing chemicals for their toxicity has relied on reporter genes, which can take 24 hr to deliver results. A new approach from North Carolina State University, however, uses a modified protein that emits light when binding occurs—effectively signaling its safety.
