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.

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.
