Acai (pronounced “ah-sigh-ee”) is a small berry with a deep purple color. It is a potent source of antioxidants, including ferulic acid and epicatechin. According to in vitro research, açai has higher antioxidant content than cranberry, raspberry, blackberry, strawberry, or blueberry, but that doesn’t necessarily mean it is the best antioxidant—just one of many to choose from when it comes to your skincare products.
