This set of 4 silicone cups are ideal for those who enjoy the benefits of cupping. The cups physically create a vacuum on the skin, reversing pressure away from the body which pulls up on tight, deep muscle tissue. This process then releases any stagnant blood and lymph to flow freely. Cupping offers a plethora of benefits including relieving chronic muscle soreness, increasing circulation to help relieve muscle tension and promote cell repair, reducing the appearance of cellulite, flushing out built-up toxins through the lymphatic system, promoting deep relaxation to move through your entire body, removing edema to helps reduce scarring as well as clearing congestion from the lungs. The cups feature strong, extra-thick silicone and have been designed with rounded rims for ease of handling and maximum suction. These softer, pliable cups are widely used in massage therapy because, unlike other types of traditional cupping, they can either be used on a single, focused area or in stroking sweeps around a tight area of the body. Due to the superior elasticity of silicone, these cups work well in curved areas of the body such as ankles, knees, wrists and elsewhere that most cupping devices fail. This set comes with 4 transparent cups with diameters of 1.2", 1.7", 2.0" and 2.5". It also includes an attractive velvet bag for travel and storage. Cupping has also been shown to improve varicose veins, clear colon blockages, relieve indigestion and help resolve chronic muscle tightness and pain faster than massage therapy alone. These silicone cups can be used in the traditional stationary manner or for deep tissue massage. Since they are soft, the therapist can control the degree of suction on a client's skin. Facial cupping can also be used to help unblock your sinuses. To clean, wash the cups with hot water and dish soap. Let air dry or use a clean cloth to wipe dry.
