Science
Mechanism of Action
This ingredient functions primarily as an antioxidant by directly neutralizing free radicals and bolstering the skin's intrinsic defense systems through the activation of the Nrf2-antioxidant response element pathway. It also exerts significant anti-inflammatory effects by inhibiting key pro-inflammatory mediators, including cytokines and prostaglandins, and modulating neutrophil activity. Additionally, it offers skin conditioning properties, promoting softness, smoothness, and hydration, while contributing to a stronger skin barrier. Its antimicrobial potential may help address acne-causing bacteria, and its antioxidant action can further assist in brightening skin by reducing oxidative stress that contributes to hyperpigmentation.

Key findings
- 01 Formulations containing parthenolide-free feverfew extract demonstrated efficacy in concentrations ranging from 0.001% to 20% for improving various signs of skin aging, such as firmness, tone, texture, and the appearance of wrinkles.
- 02 Purified feverfew extract was observed to enhance the body's natural antioxidant response (ARE activity) in a dose-dependent manner and effectively reduce free radicals present on the foreheads of human subjects.
- 03 A gel cream formulation combining purified feverfew with oat significantly improved skin barrier function and hydration, while notably soothing irritated skin in individuals with dry and irritant-sensitive skin, demonstrating excellent tolerability.

The Formula
Formulation
Synergies
- Combines well with ingredients like oat to enhance skin barrier function and hydration for sensitive skin.
Conflicts
- Parthenolide, a component of the plant, is a known sensitizer and can cause contact allergic dermatitis. Formulations must be parthenolide-free.
Safety
Safety Profile
The Cosmetic Ingredient Review Board (CIR) has not yet evaluated this ingredient. While the whole plant extract, particularly if it contains parthenolide, can be a potent skin sensitizer, 'purified feverfew extract' or 'parthenolide-free' versions are generally regarded as safe for topical cosmetic use. Individuals with known allergies to the Asteraceae/Compositae plant family (e.g., ragweed, daisies) should exercise caution.
