Some folks pointed to the St. Ives apricot scrub lawsuit as evidence. The suit accused the popular skincare company of using crushed walnut powder in the product that led to "microscopic tears in the skin, exposing it to infections and irritation," according to Glamour.
“Crushed walnut powder sounds like it would be harmless—after all, it's just powder—but it's far from it,” the site reported.
In an interview with Business Insider, New York dermatologist Marisa Garshick said it's best to avoid harsh scrubs like the walnut scrub to get that desired glowy skin look.
“As an alternative, I recommend either chemical exfoliants, which are products containing glycolic acid, lactic acid among others which help to eliminate dead skin cells, or gentle polishing powders that are not designed to be rough on the skin,” she said, adding exfoliants should only be used a few times per week.
