Before battle, samurai warriors gently exfoliated and deeply cleansed their pores so they could slay foes with one sexy glance. Become an aesthetic warrior with today's deal. For $55, you get your choice of one of two detoxifying services from Acqua di Roma Naturopathic Spa and Salon at its studio in historic Jackson Square. Schedule an appointment for one of the following detoxifying services:

• An hour of closed-system certified colon hydrotherapy to improve overall digestive health. Rid your body of stubborn toxins via a gentle, soothing stream of purified water. The procedure is comfortable and cleansing (a $110 value).

• An hour in the infrared sauna plus a 30-minute ionic foot bath. The sauna allows you to sweat out pain and pounds while stimulating the immune system and improving tissue elasticity. The foot bath submerges your feet in warm, soothing, ionized water that may suggest subtle hints of lemon, chives, and eternity. Ion baths use a field of non-invasive electromagnetic energy to draw out cellular-level toxins and pollutants (a $110 value).

Situated below a former bank, Acqua di Roma has transformed the cold aura of currency into a gorgeous spa environment that sooths the soul like a warm biscuit filled with jazz notes. Treatment rooms are situated in what were once underground security vaults. Gone are the padlocks and the daily jewel heists; they've been replaced with neutral-hued walls, wood floors, dim lighting, and exquisitely selected artwork, including a wall frescoed with a Gustav Klimt work. Some details have been preserved, such as doors framed by metal rivets that remind the visitor of what once was while adding an edge of character to the spa's appearance.
