Skin-lightening Challenges
By: Zoe Draelos, MD, Dermatology Consulting Servic…
A number of skin-lightening ingredients are on the market, as this review describes, but many of them are burdened by safety or efficacy baggage. Some do not inhibit melanin in vivo, while others may be toxic or face penetration issues. Additional research is required to develop a truly effective and safe OTC skin lightener.

Measuring the Antioxidant Potential of an Acai Extract
By: Karina Coyado Bispo, Beraca
The antioxidant potential of cosmetic materials can be evaluated by several methodologies, including a commercial kit that measures total antioxidant status, as illustrated here with a commercial extract from the fruit of the açaí, a Brazilian palm tree. Applications in antiaging products are suggested.

Drawing the Line on Wrinkles
By: Diane Bilodeau, PhD, and Isabelle Lacasse, Atr…
A new effective strategy to reduce the appearance of fine lines and wrinkles involves supporting the production of structural proteins involved in skin cohesion at the dermal-epidermal junction with a new biomimetic peptide created by solid phase.

Treating Wrinkles with Dimethylaminoethanol, Retinol and Mineral Salts
By: C. Bertin, C. Robert, M. Jousselin and N. Issa…
A placebo-controlled study was conducted to determine if the appearance of wrinkles on facial skin could be improved by a combination of three cosmetic ingredients: dimethylaminoethanol, retinol and mineral salts. Both clinical assessment and video analysis of cutaneous replicas showed a significant improvement of the wrinkle appearance.

An Aquaporin-inspired Lipid Concentrate for Mature Skin
By: M. Farwick, B. Santonnat, P. Lersch, K. Koreva…
The authors describe a novel multi-lamellar concentrate based on ceramide technology and newly identified cell-signalling molecules. This skin-identical blend provides skin protection benefits and is shown to increase molecular markers for water management and barrier components that decline during aging, thus improving skin barrier function, moisturization and elasticity.

From the Sea: Algal Extracts for Skin Homeostasis
By: Diane Bilodeau and Isabelle Lacasse, Atrium In…
The authors discuss the abilities of marine-derived active ingredients to protect the skin from barrier disruption, aging, free radicals and inflammation. Four marine species are examined that provide such benefits via various sulfated polysaccharides and polyphenols.

Bench & Beyond: Stimulating Sirtuins' Antiaging Appeal
By: B. Brewster, Cosmetics & Toiletries Magazine
Nicotinamide, the amide of niacin or vitamin B3, is used to treat arthritis. It also has demonstrated anti-inflammatory actions that may be of benefit in patients with inflammatory acne vulgaris. Nicotinamide, therefore, would appear to play a positive role in inhibiting inflammation but a negative role in aging. Are there other ways to stimulate sirtuins?

Tetrapeptide Targets Epidermis Cohesion
By: G. Pauly, MD; P. Moussou, PhD; J.-L. Contet-Au…
Most antiaging products claim to act on the dermis; however, the epidermis, a key element of cutaneous aging, is often forgotten. In the present study, researchers selected an acetylated tetrapeptide for its effect on epidermis cohesion, triggered by activity on syndecan-1 and collagen XVII; these effects are confirmed in vivo.

Sirtuins: A Breakthrough in Antiaging Research
By: I. Imbert, C. Dal Farra and N. Domloge, Vincie…
This article reviews the first scientific evidence confirming the presence of sirtuins in the skin, as well as their role in cell survival, senescence and longevity. This vital discovery could lead the way to new and innovative types of antiaging cosmetic ingredients that activate sirtuins.
