Interpersonal Hormone Transfer and Cosmetic Contact Allergens

It is possible that the transdermal transfer of applied hormones is of clinical relevance to personal care products. An estimated 1–3% of the population is allergic to a cosmetic product or ingredient contained therein.

Gauging UV Light Exposure to Reduce Vitamin D Deficiency

Vitamin D is critical to human health and the best source is from natural UVB light. However, contrary to the benefits gained are the well-documented damaging effects of sun exposure. In response, described here as a complementary approach to sun care is the development of an accurate gauge of UV exposure to produce optimum levels of vitamin D before sunburn results.

Consumer Perspective: Achieving an Even Skin Tone

Consumers are becoming more aware of the evenness of their skin tone, and it has become an important concern. Consequently, the primary focus of anti-aging skin care has shifted from reducing wrinkles to evening out skin pigmentation

Molecular Targets of Aging Processes

The purpose of this article is to discuss some key target molecules and receptors involved with aging mechanisms. As scientists learn more about the biochemical processes involved with aging, an increasing number of these loci are discovered that could be selected as targets for cosmeceutical ingredients with the final goal of an end-product with good anti-aging benefits.

Types of Skin Aging

The process of skin aging is complex and multifactorial, as structural, functional and aesthetic changes happen at a variable rate. It is misleading to consider skin aging as a uniform biological event; several distinct biological processes may occur concurrently. There are five types of skin aging, including: intrinsic, extrinsic, lifestyle, hormonal or catabolic.

Unexpected Lessons in Dermatotoxicology: De minimis Magnesium++

Traditional dermatotoxicologic investigations focus on dermatitis as well as potential systemic effects but rarely have they focused on trace ions. The following lesson opens new avenues of thought and investigation for intimate care product developers, since the trace ions described may dramatically impact the end product.

Is Asian Skin Really Different from Black or Caucasian Skin?

It often is claimed, particularly in East Asia, that Asian skin is more sensitive than Black or Caucasian. To explore this claim, the author investigates the current literature in this review and concludes there are two aspects being overlooked: the skin’s capability to cope with perturbations and the route of penetration.

Culture Shift: Rethinking the Role of Commensal Microflora of the Skin in Cosmetic Formulation

Much like bacteria in the gut, the skin’s microbiome plays an important role in skin health by excluding harmful transients and educating the immune system. The application of pre- and probiotic concepts in cosmetics presents a novel approach. While formulation with probiotics may pose challenges, the use of prebiotics and bacterial lysates, discussed here, may be a viable alternative.

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.
