System Verdict
This is a vitamin C serum with no vitamin C—mostly a basic hydrating formula wearing a brightening label. The efficacy score is 3.0/5 because the provided INCI contains no L-ascorbic acid or vitamin C derivative, so it cannot substantiate the product's central brightening or antioxidant claim. Glycerin, cassia polysaccharide, and sodium hyaluronate can support hydration, while vitamin E is present but its concentration and stability are unclear; there is no disclosed pH, no meaningful brightening active, and botanical extracts near the lower half of the list should not drive a high treatment score. The safety score is comparatively favorable because the formula contains no listed fragrance, essential oil, denatured alcohol, harsh surfactant, or retinoid.
