Consumer Perspective—The Feel Good Factor in Skin Care

The feel good factor in skin care stems from the integrity of the skin barrier. A recent theory hypothesizes that the injured epidermis can affect emotional state and act on the brain, which this author supports based on client feedback.

A Dermatological View—Innovations in Hyaluronic Acid

HA is critically important to dermatologists and to cosmetic scientists, as it maintains the moisture in skin, and loss of accessible HA results in wrinkling and changes associated with aging. Replacement of such HA is the goal of many cosmetic and cosmeceutical techniques and reagents.

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.

A Dermatological View—Interpreting Placebo Response in Clinical Trials for Psoriasis

By comparing response rates of placebo versus active drug groups in psoriasis RCTs evaluating biologic agents, the authors of this column sought to clarify factors contributing to placebo responses and their implications in improving clinical trial design to determine more accurate drug efficacies.

UVA Protection Through Strawberry Anthocyanins

Scientists at the Università Politecnica delle Marche, The University of Barcelona, the University of Salamanca and the University of Granada have produced an extract of strawberry to quantify the ability of the fruit to protect the skin.

Nano-sizing Chitosan for Wound Healing, Anti-aging

Mihaela Leonida, PhD, a professor of chemistry at Fairleigh Dickinson University, investigated the antibacterial properties of chitosan for cosmetic and pharmaceutical uses. She found that the material exhibited enhanced effects after being nano-sized.

Consumer Perspective—Skin Types and Sensory Experience

Sophisticated texture and fragrance as part of a formulation’s aesthetics are important to the discerning consumer, and skin type is the primary influence behind how the consumer perceives a skin care product. For example, consumers with dry skin require a richer moisturizer, even though the product should absorb quickly for a smooth finish.

New Skin Research from Beiersdorf Tracks Skin Chonology

In a collaboration with researchers at Charité University Medicine Berlin, Beiersdorf scientists were able to demonstrate the existence of an inner clock in human skin cells, which controls skin regeneration among other things.
