What it is
An extract derived from the flowers and leaves of Silene uniflora (sea campion), a plant native to coastal regions of Europe. It is typically obtained through solvent extraction and contains flavonoids and other polyphenolic compounds believed to have antioxidant and anti-inflammatory activity.
How it works
The flavonoids in Silene uniflora extract are thought to scavenge free radicals, reducing oxidative stress on the skin. Its anti-inflammatory potential may help calm irritation and redness by modulating skin's inflammatory response, though the exact mechanisms are not yet fully characterized in human skin.
Pros
Gentle on skin
Low irritation and comedogenic risk make it suitable for sensitive and acne-prone skin types.
Natural antioxidant
Contains flavonoids that may help protect skin from free radical damage caused by pollution and UV exposure.
Cons and cautions
Limited research
Most evidence comes from lab studies; there are few human trials proving its effectiveness in skincare.
Rare allergen potential
As a botanical extract, it can cause allergic reactions in individuals sensitive to related plant species.
Best for
- People with sensitive or easily irritated skin looking for gentle soothing ingredients
- Those interested in botanical, plant-based skincare formulations
Use caution if
- Individuals with known allergies to plants in the Caryophyllaceae family (carnations, pinks)
Usage tips
Safety summary
Silene uniflora extract is considered safe for topical cosmetic use with low irritation and comedogenic potential. As with any botanical, patch testing is recommended for those with plant allergies.
