Our take
Is Green 3 (CI 42053) a Good Ingredient?
It's Fair because it functions purely as a colorant to improve product appearance and offers no direct skin benefit. A small subset of users may experience irritation, so its value is aesthetic rather than performance-driven, which keeps it from a higher rating.
