Ingredient review
Loureiro Cinnamon Bark Extract
INCI: Cinnamomum Loureiroi Bark Extract
A potent antioxidant bark extract that can help protect skin from environmental stress, but may cause irritation in sensitive individuals due to its natural aromatic compounds.
In plain English
This is an extract from the bark of a specific type of cinnamon tree (Cinnamomum loureiroi). In skincare, it's valued for its ability to fight free radicals (unstable molecules that can damage skin cells) and for its natural scent. However, because it contains strong aromatic oils like cinnamaldehyde, it can be irritating for some people, especially those with sensitive or reactive skin.

Research notes
