What it is

Ailanthus altissima fruit extract is a natural ingredient derived from the fruit of the Ailanthus altissima tree, a fast-growing tree native to China and Taiwan. The extract is rich in compounds like quassinoids and flavonoids, which are thought to have antioxidant and anti-inflammatory effects.

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 may also help reduce redness and irritation by calming inflammatory pathways in the skin.

Pros

Natural antioxidant source

Contains flavonoids and quassinoids that can help protect skin from free radical damage, which may reduce signs of aging over time.

Potential soothing effect

Early research suggests anti-inflammatory properties that could help calm redness and irritation, making it a gentle option for some skin types.

Cons and cautions

Limited research

Most studies are lab-based or on animals; there are few human trials confirming its benefits in skincare, so effectiveness is not guaranteed.

Allergy risk

As a plant extract, it can cause allergic reactions in people sensitive to Ailanthus species, especially those with pollen allergies.

Best for

  • People looking for natural antioxidant ingredients in their routine
  • Those with normal to combination skin seeking gentle protection

Use caution if

  • Individuals with known allergies to Ailanthus or related plants
  • Anyone with very sensitive skin who prefers well-studied ingredients

Usage tips

Patch test before using a new product containing this extract, especially if you have sensitive skin or allergies.
Use in combination with other well-studied antioxidants like vitamin C or E for a more robust protective effect.

Safety summary

Ailanthus altissima fruit extract is considered low-risk for most people when used in cosmetics at low concentrations. However, due to limited safety data and potential allergenicity, it's best for those without plant allergies and should be patch tested.

Research notes

Current evidence is emerging, with a few lab studies showing antioxidant and anti-inflammatory activity. No robust clinical trials on human skin exist yet, so claims are based on preliminary data.

Common label clues

Typical concentration
Typically used at 0.1% to 2% in leave-on products
Regulatory status
