Spa at Four Seasons Resort Scottsdale at Troon North, in Arizona, US, has introduced targeted spa add-ons, which can be added to existing facial and massage treatments for no extra time.

The treatment enhancements cost USD$10 (7.49 euro, £6.24) each and can be added to Swedish or therapeutic massages, or facial treatments 50 or 80 minutes long.

Spa director Lia Rowland said guests often have a specific area of concern they need treated, such as dry skin or tight shoulders, but do not have time for an additional service.

"The Spa Enhancements menu makes it easy to address a specific area with a series of cost-effective, simple treatments that increase the effectiveness and relaxation of any standard facial or massage," she said.

The menu includes the Skin Quencher, which treats skin to a shea butter massage and desert salt scrub, the Head in the Clouds, designed to ease tension headaches and relief to allergy and sinus pressure, Pucker Up for the lips, and Deal Me a New Hand, which focuses on the arms and hands.

The spa has 14 treatments rooms and treatments include seasonal, indigenous and innovative skin and body treatments, scrubs, clay wraps, facials and massages.
