Science
Mechanism of Action
This ingredient utilizes capsaicin, derived from *Capsicum frutescens*, which interacts with Vanilloid Receptor Subtype 1 (VR1) on sensory neurons. This interaction opens an ion channel, allowing cations to enter cells and transmit a signal, resulting in a warming sensation. The *Lactobacillus* fermentation process increases the solubility of capsaicinoids and crucially mitigates the typical dermal irritation. Furthermore, it boosts microcirculation for improved nutrient and oxygen delivery to skin cells, provides antioxidant protection from compounds like ascorbic acid and glutathione, and promotes active skin cell renewal for enhanced metabolism and radiance.
