Usage recommendations
Use the pump in short, regular sessions and avoid excessive suction. Start gently and increase vacuum gradually while monitoring comfort and skin response. Do not use on damaged or irritated skin. If you have a medical condition or take blood-thinning medication, consult a healthcare professional before use. Clean and dry all components after each session and store in a dry place.
