Epidermal Permeability Barrier and Other Topics

A historical review on the epidermal permeability barrier: Elias has published a historical review on the epidermal permeability barrier dating from the early days at Harvard to newly emerging concepts. This is a must-read article if you are the least bit interested in skin physiology. I will attempt to cover the highlights here. Elias begins with the statement, “Perhaps no tissue is so physically maligned by processing for light/electron microscopy as is the stratum corneum (SC). To further complicate matters, no tissue of such critical importance for survival has been so intellectually maligned as well.” He then traces the work of now famous investigators including Kligman, Blank and Scheuplein.

UV-Induced Stress and Other Topics

Care Boron and manganese salts and keratinocytes: Chebassier et al report on the stimulatory effect of boron and manganese salts on keratinocytes. Keratinocyte proliferation and migration are essential for the reconstruction of the cutaneous barrier after skin injury. Interestingly, thermal waters which are rich in trace elements (e.g. boron and manganese) are known to improve wound healing.

Vitamin P on skin dullness: Hosokawa reviews the effect of vitamin P (bioflavonoids) on skin dullness and its application to cosmetics. The color of the skin is known to reflect the blood flow within it. Because the concentration of melanin is low in the lip, and the horny layer in the lip area is thin, the dullness of lip was presumed to be influenced easily by the color of blood. Researchers studied the physiological differences between colorful and dull-colored lips by measuring blood flow and oxygen saturation. They found that dull-colored lips and the corner of the lips (generally dull-colored compared to the center of lips) show relatively poor blood flow and a lower degree of oxygenation.
