Within the embryonic/fetal development program, skin is of major importance. Much of the activity in skin development is centered around formation of the epidermis, which ultimately generates the stratum corneum. The present article touches the surface of the structure and function of neonatal skin.

This review of literature suggests that crosstalk between the stratum corneum and nerve fibers in the epidermis is the process by which itch is transmitted to the central nervous system. A rationale is presented for using moisturizers to reduce itch.

Like you, I have attended an astounding number of scientific conferences and have read seemingly unending technical papers dealing with what most of the time are topics of interest to cosmetic chemists. While we always can learn from these meetings and articles, it seems to me that there is a real lack of technical controversy. We sit and quietly accept what is heard as gospel. While we may not agree, we nevertheless just sit back and don’t ask the hard questions. Does this make sense? Was the test design reasonable? Did they use the proper controls?
