Score terms in plain English

Irritation risk

low

Less likely to sting, burn, or bother most users, though sensitive skin can still react.

Clogging risk

low

Less likely to feel heavy or contribute to clogged pores for most skin types.

Evidence level

emerging

The ingredient may be promising, but claims should be treated more cautiously.

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

Usage tips

Use in a serum or moisturizer applied after cleansing and before sunscreen for daytime antioxidant protection.
Pair with other antioxidants like vitamin C or ferulic acid for a synergistic effect.

Safety summary

Sambucus Williamsii Stem Extract is considered safe for topical use in cosmetics. Allergic reactions are rare, and no significant toxicity has been reported at typical usage levels. As with any botanical, patch testing is recommended for those with sensitive skin or plant allergies.

Research notes

Research on this specific extract is emerging. Studies on related elderberry species show antioxidant and anti-inflammatory activity in vitro, but direct clinical evidence for skin benefits is limited. More human studies are needed to confirm efficacy.

Common label clues

0.1% to 2%
Regulatory status
Generally recognized as safe for cosmetic use in the US and EU when used at typical concentrations. No specific restrictions apply.
Common uses
Serums, Moisturizers, Toners
Environmental note
Sourcing from cultivated elderberry plants is generally sustainable, but wild harvesting should be avoided to protect natural populations.

Good to know

  • The extract is often a byproduct of elderberry fruit harvesting, making it a more sustainable ingredient choice.
  • It may appear on labels as 'Sambucus Williamsii Stem Extract' or simply 'Elderberry Stem Extract'.
