Ingredient review

Brucea Amarissima Gall Extract

INCI: Brucea Amarissima Gall Extract

A gentle plant extract with antioxidant potential, but research is still early and benefits are not yet well-established.

beautyskincareantioxidant

In plain English

This ingredient comes from the galls (abnormal plant growths) of the Brucea amarissima tree, which is native to parts of Asia. In skincare, it's used mainly for its antioxidant activity, meaning it may help protect skin from damage caused by free radicals (unstable molecules from pollution, UV, and stress). It also has some soothing properties, making it a candidate for calming irritated skin. However, most of the evidence comes from lab studies, not human skin trials, so its real-world effects are still being explored.

What it is

A natural extract derived from the galls of Brucea amarissima, a tree in the Simaroubaceae family. Galls are plant tissue growths that often contain concentrated bioactive compounds. The extract is rich in quassinoids and other phytochemicals with antioxidant and anti-inflammatory activity.

How it works

In a cosmetic product, Brucea amarissima gall extract works by donating electrons to neutralize free radicals, thereby reducing oxidative stress on the skin. It may also inhibit certain inflammatory pathways, helping to calm redness and irritation. As a skin conditioning agent, it can help maintain the skin's moisture barrier and overall appearance.

Pros

Gentle antioxidant

Provides antioxidant protection without common irritation, making it suitable for sensitive skin types.

Soothing potential

Early research suggests it may help calm redness and inflammation, which is helpful for reactive skin.

Cons and cautions

Limited research

Most evidence comes from lab studies; there are few human trials confirming its benefits in skincare.

Rare allergen risk

As a plant extract, it carries a small risk of allergic reaction, especially for those with plant allergies.

Best for

  • Anyone looking for a gentle antioxidant boost
  • Those with sensitive or reactive skin seeking soothing ingredients

Use caution if

  • Individuals with known allergies to plants in the Simaroubaceae family

Usage tips

Use in combination with other antioxidants like vitamin C or E for a synergistic effect.
Apply after cleansing and before heavier moisturizers to allow absorption.
Patch test before first use, especially if you have sensitive skin or plant allergies.

Safety summary

Brucea amarissima gall extract is considered safe for topical cosmetic use at typical concentrations. Irritation and allergy are rare but possible. As with any new ingredient, patch testing is recommended.

Research notes

Current evidence is primarily from in vitro (lab) studies showing antioxidant and anti-inflammatory activity. Human clinical studies are lacking, so efficacy claims should be viewed with caution.
