Ingredient review
Ambrosia Peruviana Leaf Extract
INCI: AMBROSIA PERUVIANA LEAF EXTRACT
A plant extract with potential antioxidant benefits, but limited research and a possible allergy risk for those sensitive to ragweed.
In plain English
This ingredient comes from the leaves of a plant called Ambrosia peruviana, which is a relative of common ragweed. In skincare, it's added for its antioxidant properties—meaning it may help protect skin from environmental damage like pollution and UV rays. It's also sometimes used to calm irritated skin. However, because it's from the ragweed family, people with ragweed allergies might experience skin irritation. The research on this specific extract is still very limited, so it's not a well-studied or widely used ingredient.

What it is
Ambrosia peruviana leaf extract is a botanical ingredient derived from the leaves of the Ambrosia peruviana plant, a species native to parts of South America. It belongs to the Asteraceae family, which includes ragweed, daisies, and sunflowers.
How it works
In cosmetic formulations, the extract is believed to work primarily as an antioxidant, helping to neutralize free radicals that can cause premature aging and skin damage. It may also have anti-inflammatory properties that can soothe redness and irritation, though the exact mechanisms are not fully understood due to limited research.
Pros
Natural antioxidant source
Derived from a plant, it may help protect skin from free radical damage caused by pollution and UV exposure, which can lead to premature aging.
Potential soothing effect
Some users may find it helps calm minor skin redness or irritation, making it a possible addition to soothing formulations.
Cons and cautions
Allergy risk for sensitive individuals
Because it comes from the ragweed family, people with ragweed allergies may experience contact dermatitis, redness, or itching when using products containing this extract.
Limited research and evidence
There are very few peer-reviewed studies on Ambrosia peruviana leaf extract specifically, so its benefits and safety are not well-established compared to more studied botanicals.
Best for
- Those looking for natural antioxidant ingredients in their routine
- People without known allergies to ragweed or related plants
Use caution if
- Individuals with known allergies to ragweed, daisies, sunflowers, or other Asteraceae family plants
Usage tips
Safety summary
Ambrosia peruviana leaf extract is generally considered safe for most people when used in low concentrations in cosmetics. However, due to its relation to ragweed, it poses a moderate irritation risk for individuals with known allergies to the Asteraceae plant family. Patch testing is recommended. There is insufficient data on long-term safety or use during pregnancy.
Research notes
Research on Ambrosia peruviana leaf extract is very limited. Most available information comes from traditional use and a small number of in vitro studies suggesting antioxidant activity. No robust clinical trials on humans have been published to confirm its benefits or safety in skincare.
Common label clues
- Typical concentration
- Typically used at 0.1% to 2% in leave-on products
- Regulatory status
- In the US, this ingredient is not specifically regulated by the FDA as a drug; it is used as a cosmetic ingredient. The EU CosIng database lists it as a permitted cosmetic ingredient, but no specific restrictions are noted.

- Environmental note
- Ambrosia peruviana is a wild plant that can be sustainably harvested, but large-scale cultivation for cosmetics is not yet common, so environmental impact data is limited.
Good to know
