Science
Mechanism of Action
It functions primarily as a vasodilator by interacting with TRPV1 receptors on sensory neurons, which enhances local blood flow to deliver oxygen and nutrients to the skin surface. Concurrently, its high concentration of carotenoids (such as capsanthin) and vitamins A and C neutralizes oxidative stress and mitigates light-induced cellular damage.
Research
Clinical Evidence
High confidence1%
Key findings
- 01 Dermatological patch testing at concentrations up to 1.0% demonstrated zero clinical irritation or sensitization in human and animal models.
- 02 Safety evaluations by the CIR Expert Panel have reviewed successful usage in commercial formulations at levels up to 5.0%.

Dusting Analysis
Due to its potent sensory profile, many brands include this extract at 'label-only' levels (below 0.1%) to claim antioxidant benefits without triggering the characteristic warming sensation required for microcirculation enhancement.
The Formula
Formulation
Stability
Best stabilized within colloidal suspensions or nanoemulsions; requires a controlled pH environment to prevent the degradation of its sensitive carotenoid content.
Synergies
- Glycerin
- Xanthan Gum
- Broad-spectrum UV filters
Conflicts
- Extreme pH environments (highly acidic or alkaline)
- Compromised skin barriers
- Open wounds
Safety
Safety Profile
While non-sensitizing, the presence of capsaicin may cause a transient tingling or warming sensation which is a normal physiological response to the extract.
