Walmart customers may find something new the next time they’re looking for makeup and skin care products: in-store advisers offering personalized tips and recommendations. The massive retail chain is breaking out of its no-frills service model by staffing its beauty aisles with trained specialists who will suggest foundation shades to match a shopper’s skin tone or knows about a moisturizer trending on TikTok. Walmart expects to have the roles filled in more than 400 of the U.S. 4,600 stores it operates by year-end. The addition of “beauty experts” comes as Walmart, Target, specialty chains like Sephora and department stores are vying for a bigger slice of the $129 billion U.S. beauty and personal care market.
