Effective slimming actives should reduce lipogenesis, increase lipolysis, promote fatty acid release and improve skin firmness. Here, the authors describe the development of such an active based on polyglucuronic acid. Further, this material is shown to act on a new biological pathway involving the fasting-induced adipose factor (FIAF) adipokine.

The versatility of hyaluronic acid is connected to not only its size, but also to inherent opportunities within the molecule for multiple bonds and for the differentiated release of bound functional molecules. Here, ester bonds are used to introduce substitutes for the material’s alcohol groups, thus providing elasticizing, moisturizing and anti-aging benefits for skin care.

This study examines the photostability of retinol and retinyl palmitate, finding they break down rapidly when exposed to UV radiation in the 290–400 nm range. This severely reduces their concentrations in finished formulations. However, when combined with ethylhexyl methoxycrylene, these retinoids are shown to be protected against photodegradation, thus preserving their concentrations both during the manufacturing process and following application to the skin.

Moisturization in skin care formulations requires an understanding of clinical needs, relevant biological targets and the aesthetic preferences of consumers. The efficacy of moisturizers must be established in vivo due to consumer interest in both visual and instrumental validation. This review outlines the challenges of formulating moisturizing facial skin care products in line with such principles.

In the present article, a topical emulsifier blend comprising two sucrose esters at low use levels and one solid fatty alcohol is described. This composition was designed to make the use of sucrose esters in formulations more cost-effective. The blend is shown to form multilamellar liquid crystalline networks for various benefits including skin moisturization, which is assessed here.

In the present article, the authors evaluate a wild red raspberry (Rubus idaeus) extract for its beneficial compounds and potential applications in skin care. From leaf explants, raspberry stem cells were obtained to develop an extract rich in antioxidants, anthocyanins and phenolics. This extract exhibited anti-inflammatory and antioxidant activities.

Heat shock proteins (HSPs) are stress-induced and initiate a cascade of protective mechanisms when the skin is exposed to stressful conditions. In the present research, salicin extracted from white willow bark was found to influence the activity of HSPs through HSP70 and other key regulators.

Dihydroxyacetone (DHA) remains the most effective ingredient for sunless tanning; however, it poses several challenges to the formulator. Following is a review of those challenges, including: stability, malodor during the browning reaction, compatibility issues with sun protection ingredients and the generation of free radical damage. In addition, the author suggests some solutions to these challenges.

The medical community’s research toward the advancement of healing and tissue regeneration has identified Human Growth Factors (HGF) as critical components in cutaneous wound healing, suggesting their potential for skin cell rejuvenation. Here, the author reviews the present work in this area and proposes HGFs for skin regeneration and reparative products, providing an example.

Here, the authors describe mechanisms of stem cells and their potential for antiaging benefits. Cultures established from apple and grape varieties using a specialized culture technology revealed that aside from stimulating colony forming efficiency (CFE) and organogenic potential, the extracts improved the maintenance of epidermal stem cells. In addition, the grape extract provided UV protection.
