System Verdict
Decent scrub base, but the exfoliation is old-school and the fragrance lowers the appeal. The efficacy score is held up by a workable mix of mild surfactants plus two physical exfoliants, but it is pulled down by the lack of any evidence-based chemical exfoliation, the likely abrasive nature of walnut shell powder, and the fact that the soothing oat/honey ingredients sit too low to meaningfully change performance.
