Community Feedback (Reddit Highlights)

“St Ives uses ground walnut shells which can cause tearing … I would look for something that uses wax beads, or say, rice powder.

“Scrubs made with stuff like crushed walnut shell … cause micro‑tears on your skin … avoid harsh physical exfoliants on your face!

However, others say it's not necessarily problematic if used gently and correctly .
