What it is
A botanical extract derived from the stems of Sambucus williamsii, a species of elderberry. The stems contain various bioactive compounds, including flavonoids and phenolic acids, which are known for their antioxidant and anti-inflammatory properties.
How it works
In a cosmetic product, this extract works by donating electrons to neutralize free radicals—unstable molecules that can damage skin cells and accelerate aging. It also helps calm minor skin inflammation and supports the skin's natural barrier function.
Pros
Gentle antioxidant
Provides free-radical protection without the irritation sometimes associated with stronger antioxidants like vitamin C.
Soothing potential
Contains compounds that may help calm redness and minor inflammation, making it suitable for sensitive skin types.
Cons and cautions
Limited research
Most evidence for its skin benefits comes from lab studies or traditional use, not large-scale human trials.
Low concentration in formulas
Typically used at low levels (under 2%), so its effects may be subtle compared to more potent antioxidants.
Best for
- Anyone looking for a gentle, natural antioxidant in their routine
- People with sensitive or reactive skin who want extra protection without irritation
Use caution if
- Individuals with a known allergy to elderberry or related plants in the Caprifoliaceae family
