Arnica Montana Flower Extract is a plant-derived extract traditionally used in topical skincare for its anti-inflammatory, antioxidant, and bruise-soothing properties, attributed to sesquiterpene lactones (notably helenalin) and flavonoids. It is commonly included in formulations targeting redness, irritation, and post-procedure skin recovery.
| Reported effect | How often | Notes |
|---|---|---|
Allergic contact dermatitis | Uncommon | Sensitization is mainly linked to sesquiterpene lactones; more likely in those allergic to Asteraceae/Compositae plants. |
Skin irritation, redness or itching | Uncommon | Localized irritation can occur, particularly with higher concentrations or on compromised skin. |
Cross-reactivity with other Asteraceae plants | Rare | Patients sensitized to ragweed, chamomile, or marigold may react. |
Eczematous or vesicular reactions | Rare | Reported in cases of prolonged or repeated exposure in sensitized individuals. |
