1) Background: Açai berry extract is known for its high content in polyphenols and thus is\na promising ingredient for cosmetic antiaging formulations; (2) Methods: In this study, the açai extract\nwas firstly evaluated for its total phenol content (Folin Ciocalteau essay) and antioxidant activity\n(radical scavenging activityâ??DPPH; radical cation scavenging capacityâ??ABTS; ferric reducing\nantioxidant capacityâ??FRAP). Next, the açai extract was included in an O/W formulation and again\nwas evaluated for its polyphenol content and antioxidant capacity. The formulation was tested for\ngeneral characteristics, physicochemical properties and microbial stability. The proliferative effect\non human immortalized fibroblasts was evaluated by the MTT essay, while TAC assay served to\nconfirm that fibroblasts are protected from UV irradiation. The irritant potential was verified on\n20 volunteers. The study concluded with the assessment of the sensorial characteristics of the cosmetic\nformulation; (3) Results: The pure açai extract exhibited high polyphenol content and antioxidant\nactivity, and these characteristics were preserved in the O/W formulation as well. The O/W cosmetic\nformulation proved to be stable under accelerated and normal conditions, and the preservatives\nwere successful in challenging the resistance against microbial contamination. The mean irritant\npotential was zero in all volunteers, and the cosmetic formulation showed a good sensorial profile;\n(4) Conclusions: Açai extract is an interesting ingredient for cosmetic antiaging formulations.
