What it is
A natural extract obtained from the flowers of Passiflora quadrangularis, a tropical vine also known as giant granadilla. It contains flavonoids and other polyphenolic compounds that give it antioxidant and soothing properties.
How it works
The flavonoids in the extract neutralize free radicals (unstable molecules that can damage skin cells), helping to reduce oxidative stress. It also has mild anti-inflammatory effects, which can calm irritated or sensitive skin when applied topically.
Pros
Gentle antioxidant
Helps protect skin from daily environmental damage without irritation, making it suitable for sensitive skin types.
Soothing properties
May reduce redness and calm irritated skin, offering a mild anti-inflammatory benefit in formulations.
Cons and cautions
Limited research
Most evidence comes from lab studies; human clinical trials are scarce, so its real-world effectiveness is not fully proven.
Potential allergen
Though rare, people with plant allergies (especially to Passiflora) could experience contact dermatitis.
Best for
- People with normal to dry skin looking for gentle antioxidant support
- Those with sensitive skin who want a soothing botanical ingredient
