Palm-derived Dihydroxystearic Acid for Sensory and Technical Applications
By: Rosnah Ismail and Hazimah A. Hassan, Malaysian…
Dihydroxystearic acid (DHSA), derived from palm oil- or palm kernel oil-based oleic acid, offers interesting applications since its addition to oily phases and wax gels affects flow and spreading properties. Moreover, it interacts with the surfaces of pigments and fillers, improving color development as well as sensory attributes, as shown here.

ECM-derived Tetrapeptide to Counterbalance ECM Degeneration
By: Mike Farwick, Ursula Maczkiewitz, Peter Lersch…
Degradation of dermal and epidermal proteins and the reduced proliferation of collagen and hyaluronic acid in the dermis occur during aging. Thus, antiaging technologies must to correct these deficiencies to induce skin regeneration and combat the signs of aging. Data presented here demonstrates that ECM-derived tetrapeptides have the potential to counterbalance ECM degeneration.

Orthorhombic Phase Stabilization for Internal Occlusion: A New Mechanism for Skin Moisturization
By: Johann W. Wiechers, PhD, JW Solutions
While humectants and occlusive agents are the most commonly accepted approaches to moisturize skin, earlier work indicates a third approach: orthorhombic phase stabilization. In the present article, the author describes this novel mechanism of hydration and its detection by conventional and nonconventional methods, suggesting this approach could serve as a basis for all skin moisturizing therapies.

A Medicinal Plant Blend for Soothing and Anti-inflammatory Effects
By: Jongsung Lee, Eunsun Jung, Kwangseon Jung and …
The use of steroids to treat atopic dermatitis (AD) often causes side effects; thus, the authors present a blend of plant-derived materials designed as an alternative treatment or an adjuvant therapeutic agent. Through in vitro and in vivo evaluations, the blend is shown to provide effective anti-inflammatory and AD-mitigating effects.

Eye Area Problems: Puffiness, Bags, Dark Cicles and Crowsfeet
By: C Oresago, M Dickens and A Znaiden, Avon Produ…
To develop active treatment products that address eye area problems, i.e., puffiness, bags, dark circles and crowsfeet, the cosmetic chemist must better understand the biology of the eye area, the effects of aging and chronic sun exposure and how to select ingredient that will provide stuitable benefit.

Antibacterial and Anti-inflammatory Effects of a Magnolia Extract
By: Jongsung Lee, Eunsun Jung, Sungran Hur and Deo…
P. acnes can exacerbate acne as a result of the inflammatory properties of the cell wall short chain fatty acids and chemotactic factors. Here, researchers investigate the effectiveness of a magnolia extract as an acne treatment, based on the known anti-inflammatory and antimicrobial effects from magnolol and honokiol within the material.

Sensitive Skin and Skin Barrier
By: Giorgio Dell'Acqua
A relationship exists between sensitive skin and skin barrier proteins and lipids, as the author shows here. While formulations to treat sensitive skin have tended to focus on eliminating irritant ingredients and penetration enhancers, an approach is suggested to help the skin build its own barrier defense from the inside-out.

Formulating at pH 4-5: How Lower pH Benefits the Skin and Formulations
By: Johann W. Wiechers, PhD, JW Solutions
Most skin products are formulated around pH 6 but the latest research in skin biology suggests the skin is significantly more acidic—around 4.7. Here, the author shows how formulating for this natural pH can enhance the skin penetration of actives, reduce the amount of preservatives required, and increase chemical stability.
