Facial morphology is associated with subcutaneous adipose tissue (sFAT), dermal elasticity and the dermal layer structure. Thus, a fibroblast/adipocyte co-culture was developed to examine the interactions between these entities. Once their mechanisms were identified, a tiencha, or sweet tea, extract was tested for its effects on adipocytes and potential to improve facial morphology.

Obviously, microbes have been around forever; just ask Ötzi, the Copper Age Man. The point being: if you can’t beat ‘em, join ‘em. It appears the industry is taking this to heart—and skin.

The present article reviews the roles of microRNA in skin senescence, then explores how an extract of Plantago lanceolata, obtained through plant cell culture technology, regulates the genetic expression of specific microRNAs. Signs of senescence relating to dermal quality, density and thickness, and the appearance of age spots were assessed.

The cosmetics and skin care industry is constantly developing new products and technologies that aim to slow down the skin aging process. Epigenetic processes play an important role in skin aging. Several new cosmetic products target epigenetic mechanisms and have shown promising results as novel cosmeceuticals.

This review examines the efficacy and tolerability of agents such as hydroquinone, ascorbic acid and retinol to treat hyperpigmentation disorders. The authors assess the quality of studies as a tool to determine efficacy of depigmenting agents. Along with outcome, they also analyze study design, participant skin type, duration, intervention and statistical significance.

Despite its being an area of concern for many years, the percutaneous absorption of cosmetics has not been rigorously studied. Additionally, the effects of shaving on this process are relatively unknown. An overview of recent research reveals that more research in this area is required.
