Science
Mechanism of Action
This extract operates through a dual-action pathway: it suppresses the production of pro-inflammatory mediators such as nitric oxide (NO) and tumor necrosis factor-alpha (TNF-α) while utilizing catalposide and ferulic acid to neutralize free radicals. Furthermore, it accelerates tissue recovery by stimulating cellular regeneration and reducing oxidative burden at the site of damage.
Research
Clinical Evidence
Medium confidence3%
Key findings
- 01 In vivo trials demonstrated that concentrations between 1% and 5% significantly lowered dermatitis scores and prevented epidermal hypertrophy by inhibiting Th2-related factors (IL-4, IL-13).
- 02 In vitro analysis at 0.1 mg/mL confirmed potent antioxidant properties, specifically in scavenging hydroxyl and DPPH radicals at levels comparable to synthetic antioxidants like BHT.
Transparency
Dusting Analysis
Because it is a botanical extract often used for 'label claims,' many formulations include it at concentrations below 0.5%. However, clinical data suggests a minimum of 1% is required to effectively address inflammatory skin conditions and provide measurable soothing benefits.
The Formula
Formulation
Stability
Moderately thermolabile; must be incorporated during the cooling phase (below 40°C) to prevent the degradation of sensitive phenolic compounds.
Synergies
- Vitamin E
- Panthenol
- Glycerin
Conflicts
- strong oxidizing agents
- high pH environments (>7.0)
