➤Function: Vacuum cupping is a natural wellness therapy that promotes blood circulation and metabolism by creating suction through glass cups placed on the skin. Various skin reactions may occur after cupping—no need for concern. ➤Transparent Design: Crafted from high-transparency glass, this cupping set offers effortless use and easy cleaning. The clear cup body allows precise observation of skin changes, enabling accurate control over cupping duration and pressure. ➤Usage Instructions: Before treatment, pull the top lever to ensure airflow. Secure the vacuum vent at the cup's top, then pull the lever vertically about 4 times to create optimal suction. After treatment, gently lift the top lever to remove the cup. ➤Duration: Adults: approx. 10 minutes; Children: approx. 3 minutes; Adolescent girls: approx. 5 minutes; Women: approx. 7 minutes. Adjust duration based on skin sensitivity and tolerance. Extend time in winter and slightly reduce in summer. ➤ Precautions: Avoid bathing or swimming for 8 hours after use. Remove body hair and thoroughly cleanse skin before cupping. Do not use on areas with dense hair growth. Purple marks left after use will fade naturally within a few days—no need for concern.
