Ingredient review
Stellaria Extract
INCI: STELLERA CHAMAEJASME FLOWER/LEAF/STEM EXTRACT
A traditional herbal extract with promising antioxidant and anti-inflammatory potential, but limited modern safety data means caution is warranted.
In plain English
Stellera chamaejasme is a plant used in traditional Chinese medicine. In skincare, the extract from its flowers, leaves, and stems is added for its potential to calm irritation and fight free radicals (unstable molecules that can damage skin). However, because it's not widely studied in modern cosmetic science, its safety and effectiveness are not fully established, so it's best used in low concentrations and with patch testing.

What it is
An extract derived from the flowering tops (flowers, leaves, and stems) of Stellera chamaejasme, a plant native to Asia and used in traditional medicine.
