Deglycation Mechanism to Treat Diabetic, Elderly and Xerotic Skin

The non-enzymatic process of glycation affects macromolecules in the skin, causing premature aging especially under diabetic, xerotic and elderly conditions. As the present research describes, a mechanism of deglycation can be used to target these conditions using an imidazole derivate. Here, in vitro and in vivo assays on diabetic, xerotic and elderly panels show statistically significant positive results.

Sticking it to Hair Damage: Delivery Duo Protects and Repairs Inside and Out

To adequately protect hair from damage, an efficient solution should offer not only high coverage externally, but also penetrate hair to impart reparative effects internally. The present study explores the ability of a dual technology to provide these benefits, as demonstrated via analytical techniques.

Orange Roughy Oil for Sensitive Skin and Other Topics: Literature Findings

This month’s survey of recent patent and research literature describes moneymaking ideas for personal care product development including the influence of filaggrin on skin moisture, lotus extract for anticellulite and orange roughy oil for sensitive skin, among others.

Caprylyl Glycol/Phenethyl Alcohol Blend for Alternative Preservation of Cosmetics

In recent years, the safety of traditional preservatives has been called into question. Therefore, there is a need for alternatives that are effective, safe and sustainable—and that are non-controversial. In response, the present work investigates a mixture of caprylyl glycol and phenethyl alcohol, which is shown to provide antimicrobial activity in various skin and hair care formulations.

Startup Solutions: A Survey of Green and Sustainable Innovations

Today is perhaps the most active time in decades for startup firms focused on natural (non-synthetic) and sustainable materials, replacement ingredients, green chemistry and fermentation technologies. This paper surveys several of them.

Penetration of Cosmetics Into and Through the Stratum Corneum

The penetration routes of substances through the stratum corneum and how these transport pathways function are becoming better understood. Despite this progress, however, the penetration mechanisms of cosmetic formulations remain mysterious. This overview presents current knowledge on the various pathways of penetration, and suggests that even if cosmetic formulations penetrate no deeper than the surface, their efficacy may still be optimal.

Microemulsions for Sprayable Delivery and Other Topics: Literature Findings

This month’s survey of recent patent and research literature describes moneymaking ideas for personal care product development, including fish DNA fragments for antiwrinkle skin care, soy peptides in cosmeceuticals, improvements in the efficacy of DHA, organo-sulfur compounds for skin lightening, and silicone foaming and detergency, among others.

Hyaluronic Acid Intensified: Cross-linking Improves Stability, Functionality

To enhance the functionality and stability of topical high molecular weight hyaluronic acid (HA), derivatives were developed using divinyl sulfone as a cross-linker. The cross-linked HA gels formed were assessed as described here in terms of water-binding capacity, delivery of actives and stability against heat, free radicals, other chemicals and pH changes, and compared with non-cross-linked native HA.

Molecular Biology in Future Skin and Hair Care

Techniques developed in the field of molecular biology are currently being used to screen cosmeceutical ingredients for skin and hair care applications. New findings are published on a daily basis, providing insight with respect to future innovations for skin and hair health and appearance. Several relevant developments are reviewed here.

Carotenoids for Dietary Photoprotection

Sun exposure leads to the production of free radicals in skin and to damage to elastin and collagen, resulting in premature aging. Studies of consuming carotenoid-rich fruits and vegetables have shown lower incidences of skin pathology. Carotenoids are among the most efficient natural scavengers of free radicals and may be used as oral sun protection, as is discussed here.

Glycation and Skin Aging: A Review

The present article, adapted from Draelos and Pugliese*, provides a review of the chemistry involved in the glycation process to assist formulators in developing topical or nutricosmetic solutions for mature skin care.

The arNOX Enzyme: Implications for Intrinsic Aging

This article describes a membrane-bound enzyme found in skin whose activity increases as biological age increases. The enzyme, located on the external surface of fibroblasts and keratinocytes, generates free radicals. The present work identifies the biological mechanism of the enzyme and its relationship to the appearance of aging in skin.
