System Verdict
Solid acne-targeting serum with potent 10% azelaic acid, but kojic acid at just 0.1% and trace tea tree oil limit it to good, not elite, efficacy. Efficacy score of 4.5 reflects high-concentration azelaic acid (position 2, anti-acne/brightening gold standard) paired with niacinamide and tea tree water (10%, soothing/oil control), but deducts for low kojic (1,000 ppm ~0.1%, too dilute for strong brightening) and minimal tea tree oil (50 ppm, trace); antioxidants like glutathione/Tocopherol add synergy without jar instability issues; pH likely ~4-5 from buffers, optimal for azelaic.
