Cupping therapy is an ancient technique that has become common in Australian massage and TCM clinics. It uses suction cups placed on the skin to lift the tissue, and it often leaves circular marks that fade over a few days.
The therapist places glass, silicone or plastic cups on the skin and creates suction, either with heat or a small pump. The suction draws the skin and superficial muscle upward. Cups may be left in place for a few minutes or moved across the skin with oil — a technique called "sliding cupping".
The marks are not bruises in the usual sense — they come from the suction pulling blood to the surface. Many people report real relief, but the scientific evidence for cupping on its own is limited and mixed. It is best thought of as a complementary add-on to massage or other treatment, not a cure for a diagnosed condition.
Cupping is usually painless, though the suction can feel tight. Marks typically fade within a few days to a week. Tell your therapist about any blood-thinning medication, skin conditions or bleeding disorders beforehand, and avoid cupping over broken skin or varicose veins.
