A Review of Skin Hypopigmentation and Contemporary Strategies to Achieve an Even Skin Tone

Whether formulating for Asia, North America, Europe or Latin America, the cosmetic chemist will face one common demand in all these markets: an even skin tone. This article provides an overview of chemical and biological agents capable of causing hypopigmentation via interactions through different stages of the melanogenic pathway.

The Latest in Whitening Agents

In recent years, new agents, especially from plants, have been discovered and extracted to test for their depigmenting effects in vitro and in vivo. This article reviews these most recent skin whitening agents of interest, whose efficacy, mechanism and safety have been tested.

Study finds UV Nail Lamps to Be Safe

Researchers from Rapid Precision Testing Laboratories have found that UV nail lamps are safe and to not cause cancer. After the lamps became popular in the last few years for curing non-chip gel nail polish, many began to question their safety.

New Research Highlights Role of Elastin in Stretch Mark Formation

Personal genetics company 23andMe has conducted a genetic study on striae distensae (stretch marks) to identify genetic markers for the skin imperfections and determine why some individuals are more susceptible.

Sensitive Skin Syndrome: Sensory Response and Classification

Although a complete analysis of sensitive skin syndrome was recently published, research on said syndrome faces several difficulties. There is a lack of consensus in the medical and scientific communities for classifying sensory responses to irritants.

A Dermatological View—Percutaneous Penetration of Amino Acids

Skin care products containing amino acids often promote the benefits conferred on the skin by these molecules. Natural amino acids found in the skin have been found to improve the health of skin through antioxidation, membrane stabilization and increasing skin’s natural moisturizing factor (NMF).

Researchers Identify Molecule Causing Sunburn Pain

A team of researchers from Duke University, Rockefeller University and the University of California San Francisco have identified the gene that causes pain in sunburned skin.

Characterizing and Evaluating the Effectiveness of Volcanic Pumice Exfoliants

Pumice has a recognized application­­­­ as an abrasive agent to promote exfoliation of the skin. In this study, different particle size fractions of pumice sampled from several geologic occurrences in São Miguel’s island, the Azores archipelago, were used in the preparation of exfoliation formulations. Gels and soap were prepared and characterized, and their efficacy evaluated.

Stimulating Sirtuins' Antiaging Appeal

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?

Sirtuins: A Breakthrough in Antiaging Research

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.

Treating Spider Veins

Spider veins are popping up, literally, all over the world. This article attempts to establish possible causes for spider veins in addition to exploring their current and future treatment.

In Sight: Stimulating Stem Cells for Younger Skin

Stem cell research is a hot topic that cannot be ignored in today’s scientific realm. Its research may lead to the reversal of Parkinson’s and diabetes, to the growth of new organs, to strengthening bones and to healing damaged skin. The research of stem cells in conjunction with burn victims has led to innovation in another field—skin care.
