Science

Mechanism of Action

The extract operates via three specific pathways: it triggers TRPV1 receptors to stimulate blood flow and create a localized warming effect, utilizes a complex of vitamins (A, C, E) and flavonoids to neutralize oxidative stress, and disrupts bacterial membranes to inhibit biofilm formation.

Key findings

  1. 01 A 48-hour patch test at concentrations up to 5.0% demonstrated high tolerability, with only 10% of participants showing minimal transient redness.
  2. 02 Repeated Insult Patch Testing (RIPT) on 103 subjects at 0.025% confirmed no clinically significant allergic or irritant contact dermatitis.
  3. 03 Standardized irritation tests at 0.1-1.0% yielded zero irritant responses in human subjects.

Because it acts as a natural pigment and provides a 'warming' sensation at very low levels, brands often include it at trace amounts (<0.01%) for marketing claims without providing the antioxidant or circulatory benefits found at 0.1% or higher.
