Vitamin C regenerates oxidized vitamin E, creating an antioxidant recycling loop that extends photoprotection duration. Well-established in dermatological literature.
Ferulic acid doubles the photoprotective capacity of vitamin C and stabilizes it against oxidative degradation. The C+E+Ferulic combination is a gold standard in antioxidant serums.
Ferulic acid stabilizes vitamin E and enhances its antioxidant activity. Part of the well-known C+E+Ferulic synergistic trio.
Despite old myths, these work well together. Vitamin C brightens via antioxidant pathway, niacinamide via melanosome transfer inhibition. Complementary.
At very low pH (<2), niacinamide can convert to niacin causing flushing. In modern well-formulated products (pH 3-4), this is negligible.
Popular myth: "vitamin C and niacinamide cancel each other out." Based on a 1963 study at extreme pH/temperature. Modern products at pH 3-4 show no meaningful interaction.
