Sunscreen Sun Protection Factor claim based on in vivo interlaboratory variability
ConclusionIn this present paper, the authors demonstrated that using only one in vivo SPF value from one laboratory may actually challenge the reliability of the final SPF claim significantly. To reduce the consumer health risk by ensuring the reliability of the SPF claim, an average from at least 3 (ideally 4) different in vivo SPF values should be compulsory.This article is protected by copyright.

The roughness of lip skin is related to the ceramide profile in the stratum corneum
ConclusionThe relationship between lip roughness and the CER profile was clarified for the first time. The results suggest that not only the level of total CERs but also the specific CER species and their carbon numbers affect the maintenance of SC function.This article is protected by copyright.

A fundamental investigation into aspects of the physiology and biochemistry of the stratum corneum in subjects with sensitive skin
ConclusionsDespite the physiological similarities between the two groups of sensitive skin subjects, differences in their biochemistry were clearly evident. Lower levels of PCA, BH and TG activities together with a greater number of smaller and immature corneocytes indicate inferior SC maturation in the capsaicin‐sensitive subjects. The reduced maturation of corneocytes and thinner SC likely contributes to a greater penetration of capsaicin and the associated increased skin sensitivity.This article is protected by copyright.
