Walnut shell powder in plain English

Walnut shell powder is crushed walnut shell used as a scrub particle. The jagged pieces can feel harsh and may irritate or scratch skin, which can make red, inflamed acne look worse. If you like scrubs, gentle round beads or chemical exfoliants are usually easier on breakout-prone skin.

Is walnut shell powder bad for acne?

Not usually, but it is worth watching. Walnut shell powder is not a proven pore-clogger, but it can bother some breakout-prone or sensitive skin. Notice how your skin reacts when a product lists it near the top.
