What it is
Phellodendron Chinense Bark Extract is a water- or solvent-based extract derived from the bark of the Amur cork tree. It contains bioactive compounds like berberine, palmatine, and other alkaloids that give it antioxidant and anti-inflammatory properties.
How it works
The extract's alkaloids, especially berberine, help neutralize free radicals that can damage skin cells. It also appears to calm inflammatory pathways, which can reduce visible redness and irritation. In a formula, it adds a layer of protection and soothing without altering the product's texture or feel.
Pros
