“Due to client demand, Rescue Spa, a luxury day spa in Center City, now carries three-dozen bar soaps, up from just six kinds it sold three years ago. Older clients who have used commercial bar soaps for years appreciate the skin-softening benefits of natural soaps, said Kim Zimmerman, Rescue Spa’s e-commerce and marketing director. “And millennials appreciate the eco-conscious packaging, that they’re organic, and Korean beauty products are all the rage,” she said, noting that the best-sellers are natural organic Gounjae soaps selling for $14 to $19 and wrapped in traditional Korean paper called hanji. And Morihata’s black charcoal soap, $32 for 3.8 ounces, is popular among teenage boys (bought by their mothers) for bacne (acne on the back), she said.”
