Sucrose Ester Multilamellar Emulsifiers for Skin Moisturization
By: My Trinh Luu and Michel Mercier, MMP Inc., and…
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.

Raspberry Stem Cell Extract to Protect Skin from Inflammation and Oxidative Stress
By: Ani Barbulova, Annalisa Tito, Antonietta Carol…
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.

Reducing Skin Stress Response with Willow Bark-derived Salicin
By: Remona Gopaul and Helen Knaggs, PhD, Nu Skin G…
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.

Formulating Sunless Tanning Products with DHA: Current Challenges
By: Kelly Dobos, Kao Brands
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.

Human Growth Factors as Natural Healers: Current Literature and Application
By: Celeste Hilling, Skin Authority
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.

Stimulating Epidermal Regeneration with Plant-derived Stem Cells
By: Daniel Schmid, PhD, and Fred Zülli, PhD, Mibel…
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.

Is Asian Skin Really Different from Black or Caucasian Skin?
By: Johann W. Wiechers, PhD, JW Solutions
It often is claimed, particularly in East Asia, that Asian skin is more sensitive than Black or Caucasian. To explore this claim, the author investigates the current literature in this review and concludes there are two aspects being overlooked: the skin’s capability to cope with perturbations and the route of penetration.

Formulating with Surfactant Silicones
By: Anthony J. O’Lenick, Jr., Siltech LLC, and Kev…
The authors describe how the use of amphiphilic silicones or surfactant silicones has allowed formulators to efficiently incorporate silicone polymers into personal care products. These materials act by lowering the surface tension in the oil phase of a formulation, allowing for easier spreading on skin and hair.

Oral and Topical Echium Oil for Skin Benefits
By: Bhaven Chavan, PhD, and Graham Pennick, Croda …
In the present article, the oral administration of echium oil is shown to increase collagen levels in the skin as well as barrier functioning and skin conductance. When applied topically, the oil increases dermal structural proteins, which results in a reduction in fine lines and wrinkles, and inhibits UV-induced inflammation.

Improving Skin Moisturization with Polyglycerol-derived Plant Waxes
By: Paula Lennon, PhD, and Jean-David Rodier, Gatt…
While the claims used for skin care are becoming more and more varied, moisturization remains the priority. In this article, a method of improving the moisturization of cosmetics is described involving the use of a polyglycerol-derived blend of vegetable waxes to protect the skin from dehydration and to boost the moisturizing capacity of emulsions.
