Recent work indicates that the biomarker progerin, in conjunction with dysfunctioning telomeres, triggers cellular senescence. In response, trifluoroacetyl-tripeptide-2, a synthetic tripeptide, was developed to decrease progerin production, thereby regulating biological mechanisms involved in the aging process and reducing the cosmetic effects of aging, which are explored here.

Although any formulation type can pose obstacles for the cosmetic chemist, foundations are notorious for their degree of difficulty and intricacy of detail. As if it were not challenging enough to stabilize emulsions with superior aesthetics, foundations require emulsion stability while ensuring color properly develops and stays uniform throughout the product.

The category of color cosmetics referred to as foundations, also known as bases, strives to achieve a complex mix of functional, sensorial and aesthetic effects. These all-over facial cosmetics aim to hide minor skin imperfections like wrinkles and blemishes; to even and modify the skin color of the face; and to alter the light reflection capability and luminosity of the face and neck—all while maintaining a natural-looking and velvety appearance.

Guar hydroxypropyltrimonium chloride (GHPTC) is one of the most widely used cationic polymers in the personal care industry. GHTPC is employed primarily as a conditioning agent in shampoos and body washes. In many of these rinse-off products, it is also a critical deposition aid for the delivery of active ingredients and hydrophobic conditioning agents, e.g., silicones, to the skin and hair.

This first of two articles reviews transient and resident microbial populations of the human skin and how they alter with age, environment and exposure to antimicrobial agents. Considerations for the formulator of how cosmetic products may affect and be impacted by normal human flora also are provided.
