In this paper, the authors focus on the dialogue between skin epithelial cells and immune cells in the context of an inflammatory situation, i.e., psoriasis. The aim is to design in vitro models relevant to in vivo skin inflammation that can then be used to screen and evaluate potential cosmetic products.

Research shows that baby skin is different than adult skin in terms of structure, biochemical composition and function, as the authors review here. The adaptation of these skin qualities continues during the first year of life and should be considered when designing baby skin care products.

Various routes of entry into the skin exist, both through the SC as well as eccrine and transfollicular shunt routes. While these shunt routes may comprise only 0.1% of the skin surface, some chemicals that cannot penetrate the SC have penetrated via these routes. As a consequence, transfollicular research is being revived.

This review examines hormetic effects of various agents on skin biology. Recognition of this emerging biological phenomenon in dermatology could lead to markedly improved integrative assessments of animal/human skin responses to toxic substances and pharmacological agents, as well as endogenous agonists.

To develop active treatment products that address eye area problems, i.e., puffiness, bags, dark circles and crowsfeet, the cosmetic chemist must better understand the biology of the eye area, the effects of aging and chronic sun exposure and how to select ingredient that will provide stuitable benefit.

Showcasing that the health of the skin and body are truly intertwined, a recent study of a fat-synthesizing enzyme provides information on how the body processes and reacts to retinoic acid.

The decline in honeybees could be due to infections, lack of food, pesticides and breeding, but the consensus is that honeybees are in trouble.
