Troubleshooting most stability concerns in cosmetic formulations typically starts at the usual raw material classes comprising the skin care and makeup ingredient list. In skin care systems, the emulsification system, thickening ingredients, actives and emollients are usually examined. In a makeup formulation, structural items such as waxes and fillers are usually reviewed, as well as film-formers and colorants.

Nanoporous organosilica particles were developed to swell upon the addition of organic solvents. These are evaluated here for encapsulating and controlling the release of fragrance. Slower, continuous release was observed, suggesting their ability to extend sensory benefits. In addition, the stimulated release of encapsulated lidocaine was studied, and results implicate their use to deliver cosmetic actives.

To improve the appearance of dry and wrinkled lips, it is necessary to hydrate them. Here, the author describes a lipstick concept to meet this need and a formulation process to achieve it. The product was then tested for immediate and long-lasting moisturization using a corneometer, and a quantitative study was conducted to rate its usability.

A novel mechanism to increase collagen production based on improved hydroxylation of the collagen fiber is described here. In relation, the effects of a hydrophobic derivative of a-ketoglutarate on this mechanism are examined, and results indicate increases in collagen production in senescent fibroblasts in vitro. In vivo, a significant reduction in wrinkles and improvement in elasticity were observed.

Glycerol is one humectant commonly employed due to its high hygroscopic and hyperosmotic properties. It is used in cosmetics as a moisturizer and in pharmaceutical formulations as an active compound.2 Being naturally present in the skin, glycerol was quickly identified for its role in skin hydration, similar to natural moisturizing factors (NMF).

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.

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.

Cosmetic means for achieving rejuvenated skin can be positioned according to intensity of action, skin renewal speed and some functioning details, thus: gommage, scrub, exfoliation and peel represent the four rejuvenation strategies. In some regions, peel refers to aggressive treatments requiring authorized operators such as dermatologists or medical doctors. Therefore, this column will discuss only the first three methods for a better skin glow.
