Last year around this time, I had the opportunity to visit Corbu Spa & Salon at The Charles Hotel (Cambridge, MA). The new spa was a first for the historic hotel. This month, the spa is celebrating its one-year anniversary and introducing Eminence Organic Skin Care to its guests. To mark the new launch, the spa is offering guests a choice of complimentary treatments, all of which rely on the new product line. On Sept. 10-12 and Sept. 17-19, guests can experience the Taste a Facial, Organic Luscious Lip Treatment, or the Organic Bright Eye Lift, all of which are 15 minutes long and by appointment only. Needless to say, it's a great way to acquaint spa-goers with the line. How do you introduce clients to new product lines in your spa?
