System Verdict
This is a genuinely solid brightening toner, not a miracle toner. The efficacy score is driven by 3% niacinamide near the top of the formula, plus 2% arbutin, licorice extract, and a small amount of 3-O-ethyl ascorbic acid, which together support tone-evening and mild pore-focused benefits; the score is not higher because the vitamin C derivative is at a likely low level, the hyaluronic acid is only trace-level, and this is still a toner with limited treatment intensity versus a leave-on serum.
