3.8 / 5.0
System Verdict
A decent rinse-off scrub, but the exfoliation is mostly physical and the fragrance lowers the polish. The efficacy score lands at 2.9 because the formula has a gentle-enough cleansing base with glycerin and oat support, but its real exfoliating action comes from abrasives like hydrated silica and walnut shell rather than a well-controlled acid system, so results depend on manual scrubbing rather than a stronger evidence-backed treatment mechanism.
