This study describes methods used in a Korean study to calculate consumer exposure to lipstick and face creams. The average amount applied daily was estimated and compared with data collected by weighing containers before and after use. The data collected was 1.8 to 1.6 times greater than the estimate, so although the survey represented real use patterns, the actual data was more accurate.

The present article discusses a new approach to mimic lipofilling—the activation of hormesis, which is accomplished by the described encapsulated active designed to induce a transitory stress and initiate an overcompensation to reestablish homeostasis. This leads to the compensation of age-induced lipoatrophy and correction of wrinkles and folds, for a younger-looking appearance.

A zinc and copper complex generating biomimetic electricity on a physiological level is shown here to improve the signs of photoaging in preclinical and clinical studies. This complex was applied to the eye area to confirm its efficacy as an anti-aging treatment option with good skin tolerance.

This article reviews the mechanisms underlying skin irritation and sensitization, and methods used in a case study to test cosmetic products for their potential to cause irritation. It also covers the main skin conditions that can influence susceptibility to irritation, as well as ingredients affecting the mildness of cosmetic products.

Endocrine disruptor chemicals (EDCs) are a class of chemicals that has raised alarm for being linked to a wide variety of detrimental effects on human and wildlife populations, e.g., cancers, precocious puberty and obesity. Thus, there is a need to test personal care products and supplements for EDCs, which can be accomplished using the validated bioassay described here.

Botanical ingredients are interesting for their unique and complementary chemical diversities yet they are criticized for these very traits, which make quality assurance, reproducibility and good phytochemical characterization—required for successful high throughput screening, difficult. This article discusses these challenges as well as the benefits of large-scale screenings of botanical extracts that are currently used or developed for cosmetic product development.
