Core Material Advantages
Exceptional Flexibility: Silicone's high elasticity allows the jars to be easily squeezed by hand—simply press the jar to expel air, then place it on the skin, and the material's rebound creates stable negative pressure. This flexibility also ensures a tight, comfortable fit on curved body parts (e.g., the neck, lower back, shoulders, or joints), minimizing air leakage and maintaining consistent suction.
Safety & Skin-Friendliness: Most silicone cupping jars are made from food-grade or medical-grade silicone, a non-toxic, odorless material that is hypoallergenic and gentle on the skin. Unlike plastic jars that may release harmful substances when heated or glass jars that risk breaking and causing cuts, silicone jars are heat-resistant (withstanding temperatures from -40°C to 230°C) and shatterproof, making them safe for home use, even for beginners.
Durability & Portability: Silicone is highly resistant to stretching, tearing, and aging—with proper care, a set of silicone cupping jars can last 2–3 years. They are also lightweight (each jar weighs just 10–30 grams) and collapsible, fitting easily into travel bags or toiletry kits, ideal for use on the go.
