Anti-Aging Serum with Coffee berry

I have started using a serum that uses coffee berry and just after a couple of days I can already tell a difference. Its designed to rebuild and rejuvenate the skin long term. Anyone else using this or heard of coffee berry in skin care? I have done some research and discovered coffee berry is a super fruit for antioxidants. Would love to hear skin enthusiast's opinions. Thanks.

I think coffee berry was quite popular a few years ago? I remember seeing it mentioned in regard to its anti-oxidant properties. It sounds promising if you've seeing such quick results. which serum did you use? :)
