What it is
An extract obtained from the leaves of Carpinus turczaninowii, a species of hornbeam tree found in Korea and China. It contains various plant compounds like flavonoids and phenolic acids.
How it works
The extract provides antioxidant activity by donating electrons to neutralize free radicals, which are unstable molecules that can damage skin cells. This helps reduce oxidative stress on the skin, potentially slowing signs of aging and calming inflammation.
Pros
Gentle antioxidant
Provides a mild shield against free radicals without irritating the skin, making it suitable for daily use even on sensitive complexions.
Soothing potential
May help calm redness or irritation, offering a dual benefit of protection and comfort in one ingredient.
Cons and cautions
Limited research
Most evidence comes from lab studies, not large human trials, so the real-world benefits for skin are not yet fully proven.
Variable potency
The concentration of active compounds can differ between batches and brands, leading to inconsistent results.
Best for
- Anyone looking for a gentle, plant-based antioxidant
