Ingredient review
Stellaria Leaf/Stem Extract
INCI: STELLERA CHAMAEJASME LEAF/STEM EXTRACT
A gentle botanical extract with antioxidant potential, but research is limited and it's not a skincare staple.
In plain English
This is an extract from the leaves and stems of a plant called Stellera chamaejasme. In skincare, it's added to products like serums and moisturizers to provide antioxidant benefits (helping protect skin from environmental damage) and to soothe the skin. However, it's not a well-studied ingredient, so its effects are not as proven as more common antioxidants like vitamin C or green tea.

Score terms in plain English
Irritation risk
lowLess likely to sting, burn, or bother most users, though sensitive skin can still react.
Clogging risk
lowLess likely to feel heavy or contribute to clogged pores for most skin types.
Evidence level
emergingThe ingredient may be promising, but claims should be treated more cautiously.
What it is
A natural extract derived from the above-ground parts of the Stellera chamaejasme plant, which is a flowering plant native to parts of Asia. It contains various plant compounds like flavonoids and phenolics that may have antioxidant and anti-inflammatory activity.
How it works
The extract is thought to work by donating electrons to neutralize free radicals (unstable molecules that can damage skin cells), thereby reducing oxidative stress. It may also help calm skin by modulating inflammatory pathways, though the exact mechanisms are not fully characterized in cosmetic science.
Pros
Gentle antioxidant
Provides a mild antioxidant boost that can help protect skin from daily environmental damage without irritation.
Soothing potential
May help calm redness or sensitivity, making it suitable for those with reactive skin types.
Cons and cautions
Limited research
There is very little published scientific evidence specifically on Stellera chamaejasme extract in skincare, so its benefits are not well-documented.
Variable quality
As a less common botanical extract, the concentration of active compounds can vary widely between products, leading to inconsistent results.
Best for
- People looking for gentle, plant-based antioxidant ingredients
- Those with normal to combination skin seeking extra environmental protection
Use caution if
- Individuals with known allergies to plants in the Thymelaeaceae family (which includes Stellera)
- Anyone seeking a proven, high-efficacy antioxidant—better options exist
