Aristotelia Chilensis (Maqui) Excellente Antioxidante Envejecimiento Aristotelia Chilensis (Maqui) description Maqui, also known as Chilean wineberry, is a richly-colored berry that contains a potent type of antioxidant anthocyanidin known as delphinidins, which can help skin better withstand the rigors of UV light exposure (but just to be clear, this ingredient does not replace the need for sunscreen). Maqui is also a great antioxidant when consumed orally, largely due to the action of its polyphenols, flavanols, other anthocyanins, and ellagic acid, all of which work to squelch damaging free radicals that, left unchecked, can lead to health issues.
