What it is
A natural extract derived from the bark of Viburnum opulus, a flowering shrub. The bark contains compounds like tannins, flavonoids, and coumarins that contribute to its soothing and antioxidant activity.
How it works
The extract's flavonoids and other polyphenols help neutralize free radicals, reducing oxidative stress on the skin. Its tannins may provide mild astringent and anti-inflammatory effects, helping to calm irritated or sensitive skin.
Pros
Gentle soothing potential
The extract's anti-inflammatory compounds may help calm redness and irritation, making it suitable for sensitive skin routines.
Antioxidant support
Flavonoids in the extract can help protect skin from free radical damage caused by UV and pollution, supporting overall skin health.
Cons and cautions
Limited cosmetic research
Most studies on Viburnum opulus focus on oral use for muscle cramps, not topical skincare. Its benefits for skin are not well-documented.
Potential allergen
As a plant extract, it carries a small risk of allergic contact dermatitis, especially for those with plant allergies.
Best for
- Those with sensitive or easily irritated skin
- People looking for natural antioxidant ingredients
Use caution if
- Individuals with known allergies to Viburnum or related plants
