Both mass and prestige beauty saw continued U.S. sales gains during the first half of the year, according to Circana, but drivers of that growth shifted. In prestige, hair care was the fastest-growing category, up 11 percent versus the year prior. Also for the first time, e-commerce represented the largest channel for prestige skin care. “We’ve been seeing the online channel grow faster than the brick-and-mortar channel in skin care for some time now. Other highlights of the first half: Prestige skin care growth leaned more on body and sun care in the second quarter, with those subcategories rising 16 and 19 percent during the first half, whereas facial skin care led growth in the first quarter.
