Richel D'Ambra Spa & Salon

Ocean Mist Pedicure: The red Hawaiian algae bath, we are told, is meant to detoxify; the smooth mud mask to exfoliate and reduce edema. But by the time the staff gets down to business with the polish—several ocean mist spritzes later—you're too relaxed to care that they've supposedly reduced spider veins, too.
