What it is
Magnolia kobus extract is a natural ingredient derived from the kobus magnolia tree. It contains compounds like magnolol and honokiol, which are known for their antioxidant and anti-inflammatory properties.
How it works
The extract works by neutralizing free radicals (unstable molecules that can damage skin cells) and by calming inflammatory responses in the skin. This can help reduce redness and support the skin's natural barrier function.
