System Verdict
This is a genuinely strong vitamin C serum, not a fluffy antioxidant mist. The efficacy score is driven by the co-formulated vitamin C system: a stable vitamin C derivative plus L-ascorbic acid, backed by ferulic acid and a chelator, which is exactly the kind of setup that improves antioxidant stability and real-world performance. The score is not higher because the INCI gives no explicit concentration data, the serum’s low-pH vitamin C chemistry can still be irritating for sensitive skin, and several supportive ingredients are present mainly as solvents, buffers, and stabilizers rather than as major treatment drivers.
