Acai berry (Euterpe oleracea) extract is a fruit-derived ingredient rich in anthocyanins, polyphenols, and fatty acids used in topical formulations for its antioxidant and skin-conditioning properties. It may help neutralize free radicals and support skin barrier function, though robust clinical evidence for topical efficacy is limited.
