What it is
A natural extract derived from the fruit and leaves of Rubus hirsutus, a species of blackberry native to parts of Asia. It contains various bioactive compounds, including polyphenols and flavonoids, which are known for their antioxidant and anti-inflammatory properties.
How it works
In a cosmetic product, this extract works primarily as an antioxidant. It donates electrons to neutralize free radicals—unstable molecules that can damage skin cells and accelerate aging. It may also have mild soothing effects, helping to calm irritated skin by reducing inflammatory responses at the cellular level.
Pros
Gentle antioxidant
Provides antioxidant benefits without common irritation, making it suitable for sensitive skin.
Dual source
Uses both fruit and leaves, potentially offering a broader range of beneficial plant compounds.
Cons and cautions
Limited research
Most evidence comes from related berry species; specific studies on Rubus hirsutus are scarce, so effectiveness is less certain.
Lower potency
As a natural extract, its antioxidant activity may be weaker than concentrated actives like pure vitamin C.
Best for
- Anyone looking for a gentle antioxidant to add to their routine
- People with sensitive or reactive skin who want plant-based protection
Use caution if
- Individuals with a known allergy to blackberries or related plants in the Rosaceae family
Usage tips
Safety summary
Considered safe for topical use with low irritation and comedogenic risk. As with any botanical, patch testing is recommended for those with plant allergies.
