What it is
An extract made from the branches and leaves of Celastrus orbiculatus, a woody vine also known as Oriental bittersweet. The plant has a history in traditional Chinese medicine, and the extract contains various plant compounds like flavonoids and triterpenoids.
How it works
The extract is believed to provide antioxidant activity by donating electrons to neutralize free radicals, which are unstable molecules that can damage skin cells. It may also have mild anti-inflammatory effects, potentially calming redness or irritation when applied topically.
Pros

Cons and cautions
Limited research
There are very few peer-reviewed studies on this specific extract in cosmetic formulations, so its effectiveness is not well established.
Potential allergen
As a plant extract, it can cause allergic reactions in some individuals, especially those with plant allergies.
