Part of an ongoing series on the relationship between routine, stress and the skin barrier.
Neurocosmetics is a category of ingredients studied for their interaction with the cutaneous nervous system — the dense network of sensory nerve endings and signalling receptors in the skin.
The premise is that skin does not only respond to what is applied to its surface. It also responds to signalling. Some botanical extracts and peptides have been investigated for effects on the release or reception of neuromediators associated with sensations of discomfort, tightness and reactivity.
The research is genuinely interesting and genuinely early. Sample sizes are frequently small. Much of the work is supplier-led. A number of studies measure subjective comfort rather than a hard clinical endpoint. That does not make it worthless. It makes it provisional.
Our position is that this is a promising area worth formulating into, and that it should be described accurately. Where evidence exists we will cite it. Where it does not, we will say so.
Final ingredients, claims and performance will be confirmed following formulation and testing.
A useful term deserves a careful definition.
