What it is
An extract derived from the bulb of Ornithogalum umbellatum, a perennial plant native to Europe and parts of Asia. The extract contains various bioactive compounds, including flavonoids and saponins, which are believed to contribute to its soothing and antioxidant effects.
How it works
The flavonoids in the extract act as antioxidants, neutralizing free radicals that can damage skin cells. The saponins may help reduce inflammation by calming the skin's immune response. When applied topically, it forms a protective layer that supports the skin's natural barrier function.
Pros
Gentle on skin
Low irritation and comedogenic risk make it suitable for sensitive and acne-prone skin types.
Antioxidant support
Helps protect skin from free radical damage, which can contribute to premature aging and dullness.
Cons and cautions
Limited research
Most evidence comes from lab studies, not large human trials, so its effectiveness is not as well-established as some other botanicals.
Potential allergen
As a plant extract, it may cause allergic reactions in people with sensitivities to related plants.
Best for
- People with sensitive or easily irritated skin
- Those looking for a gentle, plant-based antioxidant
- Individuals seeking calming ingredients for redness-prone skin
Use caution if
- Anyone with a known allergy to plants in the Asparagaceae family (e.g., hyacinth, bluebell)
- Those who prefer ingredients with more robust clinical evidence
