The Empress Collection Is a Complete Facial Gua Sha System, Inspired by Ancient Chinese Practices, That Includes the Empress Tonic, Empress Oil, and Our Patented Empress Stone. Each Product Is Powerful on Its Own, But Together They Work Synergistically to Create a Perfect Canvas for the Skin-changing Benefits of Facial Gua Sha. Whole-plant Botanicals in the Tonic and Oil Deliver Hydrating, Smoothing, and Brightening Effects While the Empress Stone Sculpts Facial Contours by Undoing Old Expression Patterns, Moving Lymph, and Encouraging Myofascial Release.
