Testing dermal nerve responses with electrodes is the subject of a 2002 patent application by Cognis6, based on research performed in France, where the patent was filed for. This study is a good place to begin an examination of the underlying science of neurocosmetics: “The skin is equipped with a particularly effective communication and control system of which the function is to protect the organism from the environment. This system contains a very dense system of highly specialized, outgoing autonomous nerve branches and sensory, feeder nerve branches which is distributed over all layers of the skin. The information passing through this network is processed in the central nervous system and can produce an inflammatory reaction through the antidromic propagation of impulses. The response activity of a nerve can be determined from the neuropeptides released and the receptors of the corresponding target structures.”
The nervous system can easily absorb a lifetime of study. The advent of the Internet, however, makes exploration easier; simply Google search terms such as nociceptor, Aδ fiber axons, C fiber axons, mechanotransduction, thermotransduction or neurotrophins to open a world of knowledge. The challenge is not a lack of information but the ability to sort through the vast resources now available with the click of a mouse.
Neurocosmetics is clearly only a step towards the logical goal, a REACH Certified Biodegradable Green Renewable BioActive NanoNeuroCosmetic—the inevitable topic of a future Chemical Reaction column. Our industry is clearly far from the end of its quest to understand and treat aging skin, but the possibilities for new and better products seem endless.
