This paper was presented as a keynote lecture at the IFSCC Congress 2008, Barcelona, Spain.

Cutaneous neurogenic inflammation is emerging as an underlying mechanism for several skin conditions. The intimate cross-talk between the cutaneous immune system and the peripheral nervous system is fundamental for skin biology. However, an imbalance or dysfunction results in the onset of an inflammatory state that is reinforced by the synergic and complementary action of both systems. Cumulative evidence indicates that the thermoreceptor TRPV1 is a key player of neurogenic inflammation. This receptor is activated by both physical and chemical stimuli, and its activity is potentiated by pro-inflammatory mediators. An increase in TRPV1 activity results in an increment of neuronal excitability that leads to the release of proalgesic agents that stimulate the immune system. Therefore, the TRPV1 receptor is being considered as a cosmeceutical target, and agents that reduce its activity will be useful cosmeceuticals. Keywords:
