Peptidomimetics, or synthetic bioactive peptides, have been developed that mimic the biological functions of peptides and proteins but overcome many of these challenges and limitations. Further, due to their wide range of activity, synthetic feasibility and ease of handling, they have played a vital part in biological research. This column will discuss the potential application of these short chain oligomers in cosmetics and personal care.

This work evaluates the impact of three different substrates on in vitro SPF measurements, and defines experimental conditions to improve their correlation with in vivo values. Evaluations of 32 products, shown here, led the authors to conclude that molded substrates improved repeatability and correlation with in vivo SPF values.

Lab tests on sunscreens show it takes more energy to produce mild erythema on protected skin than unprotected skin. Yet the FDA questions the need for SPFs higher than 50. In response, two outdoor studies were conducted using commercial products to challenge standing premises and determine if there is a measurable difference in an SPF 100 and SPFs of 50 or less.

Procter & Gamble (P&G) researchers, including Mary Begovic Johnson, principal scientist, may have come closer to finding the "fountain of youth" in cellular bioenergetics. As she explains, the role of this discipline in skin’s appearance has been identified, along with ingredients that can restore energy to cells.

Melanin-reducing agents are considered safer alternatives to melanocytotoxic compounds. Thus, the present work examines the effects of 3-O-ethyl ascorbic acid on enhancing skin tone by reducing melanin through the inhibition of tyrosinase-related proteins. Described studies include tyrosinase and TRP-2 inhibition, in vitro and ex vivo melanin inhibition, clinical whitening, DNA protection and collagen synthesis.

Ultraviolet and infrared exposure are sources of premature skin aging, characterized by solar elastosis and extracellular matrix degradation. Polygonum aviculare extract is a cathepsin G inhibitor, and is shown here to oppose photoaging and infra’aging by improving skin firmness and elasticity, in turn reducing the appearance of wrinkles.
