Ingredient review
Chenopodium Ambrosioides Leaf Extract
INCI: CHENOPODIUM AMBROSIOIDES LEAF EXTRACT
A traditional herbal extract with limited modern skincare research; may offer antimicrobial benefits but carries a moderate risk of skin irritation.
In plain English
This is an extract from the leaves of a plant called Chenopodium ambrosioides, also known as Mexican tea or epazote. In skincare, it is sometimes added for its herbal scent and because it may help fight certain bacteria on the skin. However, there is not a lot of strong scientific evidence to confirm how well it works or how safe it is for all skin types. Because it contains strong-smelling oils, it can be irritating for people with sensitive skin.
