INCI: PRUNUS SPECIOSA BARK EXTRACT
A gentle botanical extract with antioxidant potential, but research on its specific benefits for skin is still limited.

In skincare, it is used as an antioxidant to help protect skin from environmental stressors like pollution and UV damage. It also has soothing properties that may calm irritated skin. However, most of the evidence for its benefits comes from traditional use and lab studies, not large human trials.

What it is
Prunus Speciosa Bark Extract is a natural plant extract obtained from the bark of the Oshima cherry tree (Prunus speciosa). It contains various bioactive compounds, including flavonoids and phenolic acids, which are known for their antioxidant and anti-inflammatory activities.
How it works
In a cosmetic product, this extract works primarily by donating electrons to neutralize free radicals—unstable molecules that can damage skin cells and accelerate aging. It may also help reduce inflammation by inhibiting certain enzymes involved in the inflammatory response, leading to calmer, less reactive skin.
Pros
Gentle antioxidant
Provides free radical protection without common irritation, making it suitable for sensitive skin types.
Soothing potential
May help reduce redness and calm inflammation, offering a dual benefit of protection and comfort.
Cons and cautions
Limited research
Most evidence comes from lab studies or traditional use; large-scale human trials on skin benefits are lacking.
Allergy risk
As a plant extract, it may cause allergic reactions in people sensitive to cherry tree pollen or related botanical families.
Best for
- Anyone looking for a gentle, natural antioxidant in their routine
- Those with sensitive or easily irritated skin who want soothing ingredients
Use caution if
- Individuals with known allergies to cherry tree pollen or related plants should patch test first
Usage tips
Safety summary

Research notes
Research on this specific extract is sparse. Most supporting data comes from studies on related Prunus species or general flavonoid antioxidants. Early lab studies suggest antioxidant and anti-inflammatory activity, but more human clinical trials are needed to confirm efficacy for skin.
