Ingredient review
Euphorbia Lathyris Seed Extract
INCI: EUPHORBIA LATHYRIS SEED EXTRACT
A plant extract with potential antioxidant and soothing benefits, but limited research and a known risk of skin irritation for sensitive individuals.
In plain English
Euphorbia lathyris seed extract comes from the seeds of a plant sometimes called caper spurge. In skincare, it is added to products like serums and moisturizers for its ability to help calm the skin and fight damage from environmental stressors. However, because the plant belongs to a family known for irritating sap, this extract can cause redness or stinging in some people, especially those with sensitive skin. It is not a well-studied ingredient, so its benefits are based on traditional use and early research rather than large clinical trials.

What it is
Euphorbia lathyris seed extract is a natural ingredient obtained from the seeds of the Euphorbia lathyris plant, a member of the spurge family. The extract contains various compounds, including diterpene esters and flavonoids, which are thought to contribute to its antioxidant and soothing properties.
How it works
In a cosmetic product, this extract is believed to work by providing antioxidant compounds that neutralize free radicals, which can damage skin cells and accelerate aging. It may also help reduce visible redness and irritation by calming inflammatory pathways in the skin. However, the exact mechanisms are not fully understood and are based on limited studies.
Pros
Natural antioxidant source
Provides compounds that may help protect skin from environmental stressors like pollution and UV damage, which can lead to premature aging.
Potential soothing effect
Early research suggests it may help reduce visible redness and calm minor skin irritation, making it a candidate for sensitive skin formulas if well-tolerated.
Cons and cautions
Irritation risk
The plant family is known for producing irritating sap, and this extract can cause stinging, redness, or allergic reactions, especially on compromised or sensitive skin.
Limited research
There are very few human studies on this specific extract in skincare, so its benefits and safety profile are not as well-established as more common botanicals.
Best for
- People with normal to oily skin looking for a natural antioxidant
- Those who tolerate botanical extracts well and want a soothing ingredient
Use caution if
- Individuals with sensitive, reactive, or eczema-prone skin
- Anyone with a known allergy to plants in the Euphorbiaceae family
