The efficacy score is driven by a mild combination of lactobionic acid and papain, with niacinamide and multiple humectants adding some support; however, the exfoliating system sits late in the INCI, so the likely concentration is modest and this is more about gentle surface polishing than meaningful corrective exfoliation. The low-pH claim is directionally helpful, but there is no strong evidence here of a high-strength acid formula, so the result should be modest and skin-friendly rather than dramatic.
