What it is
An extract derived from the wood of Prunus spinosa (blackthorn), a deciduous shrub known for its dark bark and tart sloe berries. The extract is typically obtained by soaking the wood in a solvent like water or alcohol to pull out beneficial compounds such as tannins and flavonoids.
How it works
The tannins in blackthorn wood extract have a mild astringent effect, meaning they cause a slight tightening of skin proteins, which can temporarily reduce the appearance of pores and control oiliness. The flavonoids provide antioxidant activity, helping to neutralize free radicals that can lead to premature aging. It also has anti-inflammatory properties that can soothe minor irritation.
Pros
Gentle astringent
Provides a mild tightening effect that can help refine pores without the harshness of high-alcohol toners.
Antioxidant support
Contains flavonoids that help protect skin from environmental stressors like pollution and UV damage.
Cons and cautions
Limited research
Most evidence for blackthorn wood extract comes from traditional use and lab studies, not large-scale human trials.
Potential drying effect
If the extract is alcohol-based, it may strip natural oils from very dry or sensitive skin.
Best for
- People with oily or combination skin
- Those looking for a gentle astringent alternative to alcohol-based toners
Use caution if
- Individuals with known allergies to Prunus species (plum, cherry, peach)
- Those with very dry or compromised skin barriers
