A dermatologist-led institute at the University of Miami (UM) Miller School of Medicine has been established to determine the efficacy of skin care products and procedures, and to discover and treat the genes that determine aging, pigmentation and acne.

MIT and Boston University engineers have designed cells that count cellular events. Such cells could be used to count the number of cell divisions for the study of antiaging; to study a sequence of developmental stages, or to serve as biosensors to count exposures to toxins.

Multiple factors affect the integrity of cell mitochondria, leading to loss of cell function, aging and apoptosis. In skin, this is expressed in the form of wrinkles, loss of tone, etc. To combat these effects, the author describes a technology that contains mitochondria-nourishing compounds to deliver antiaging benefits.

Oregon State University researchers have discovered that the expression of CTIP2 may play a role in some skin disorders. But the research was two-fold, as the team also found the gene to control tooth enamel.

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.
