(Gayot) - Since the opening of the world's first official wine spa in the Bordeaux region of France in 1999, high-end spas around the world have followed suit. While the true, trademarked Vinothérapie treatments are only available at Caudalie-affiliated spas like Les Sources de Caudalie in France (the original), wine treatments — considered to firm the skin and slow down the aging process due to wine's high antioxidant content — are beginning to be incorporated into spa menus around the world.
