As one-stop shop for relaxation and beauty services, O Spa curates a menu that ranges from traditional spa massage therapies, facials, and slimming wraps to specialized treatments such as mani-pedis, eyelash extensions, and permanent makeup. The spa's technicians can use laser light to permanently reduce unwanted hair and remove tattoos clients got during their teenage years of rebellion and obsession with the Artist Formerly Known as Prince. Permanent-makeup artists fill in barren eyebrows or line the eyelids or lips, keeping facial features constantly looking fresh.
