Cupping uses suction cups applied to the skin to draw tissue upwards, in contrast to massage which presses downwards. Dry cupping is the common form in the UK, and the circular marks it leaves are caused by small blood vessels breaking under suction rather than by impact. Evidence supports short-term relief of musculoskeletal pain, with weak evidence for anything else. Sessions cost £30 to £60, often as an add-on to a massage.
Key takeaways
- Cupping pulls, massage pushes
- Suction lifts skin and superficial tissue upwards, which is the opposite of the compression used in massage.
- The marks are not bruises from impact
- They are caused by small blood vessels breaking under suction. They typically fade over three to ten days and are painless.
- Dry cupping is standard in the UK
- Wet cupping, which involves small skin incisions to draw blood, is far less common and carries genuine infection risk.
- The evidence is modest
- Reasonable short-term support for neck and lower back pain, weak or absent evidence for anything beyond musculoskeletal complaints.
- Mark colour does not indicate toxins
- The traditional claim that darker marks indicate stagnation or toxicity has no basis. Colour reflects local capillary fragility and suction strength.
- It is usually an add-on
- Most UK practitioners include cupping within a massage or acupuncture session rather than selling it alone.
- Some situations rule it out
- Blood-thinning medication, bleeding disorders, fragile skin, pregnancy over the abdomen and lower back, DVT risk and skin infections.
What cupping is
Cupping applies suction cups to the skin, creating negative pressure that draws the skin and superficial tissue upwards into the cup. It has a long history in Chinese, Middle Eastern and Eastern European traditional medicine, and reached wide Western awareness when Olympic athletes appeared with circular marks across their shoulders.
The mechanical effect is the opposite of massage. Where a deep tissue massage compresses tissue downwards, cupping decompresses it upwards. Practitioners describe this as creating space, increasing local blood flow and providing a stretch to the fascia that cannot be achieved by pressing.
Traditional explanations describe removing stagnation or drawing out pathogenic factors. The mechanistic account, which is more useful for deciding whether to try it, is simply local hyperaemia and fascial decompression.
Types of cupping
| Type | What it involves | Common in the UK? |
|---|---|---|
| Dry cupping | Static suction cups left in place for five to fifteen minutes | Yes, the standard form |
| Moving or gliding cupping | Oil applied, then cups moved across the skin under suction | Yes, often within a massage |
| Flash cupping | Cups applied and removed repeatedly in quick succession | Occasionally |
| Fire cupping | Suction created by briefly heating the air inside a glass cup | Less common, requires specific training |
| Wet cupping (hijama) | Small skin incisions made, then suction applied to draw blood | Rare, and carries genuine infection risk |
Most UK practitioners use silicone or plastic cups with a hand pump, which allows precise control of suction and carries no burn risk. Wet cupping is a different proposition entirely: it breaks the skin, so sterile technique and appropriate registration are essential, and it is worth being cautious about where it is offered.
Why it leaves marks
Sustained negative pressure causes small capillaries close to the skin surface to break, releasing a small amount of blood into the surrounding tissue. That produces the characteristic circular discolouration, ranging from pink to deep purple.
Two things are worth understanding. First, these are not bruises from impact and are usually painless, though the area can feel tender. Second, and more importantly, the colour does not indicate anything about your health. The traditional claim that dark marks reveal toxins or stagnation has no basis; intensity simply reflects suction strength, duration and individual capillary fragility, which is why people on blood thinners mark far more readily.
Marks typically fade over three to ten days. If you have an event where you would rather not have visible circles, plan accordingly.
What the evidence says
Reasonably supported: short-term reduction in neck pain and lower back pain, and short-term improvement in perceived stiffness. Several systematic reviews find modest positive effects, though studies are frequently small, of mixed quality, and impossible to blind properly given the visible marks.
Not well supported: claims relating to respiratory conditions, digestive complaints, fertility, immunity and detoxification. Cupping does not remove toxins; nothing is being drawn out of the body in dry cupping, since the skin is not broken.
NHS guidance on complementary therapies is that they should be used alongside conventional treatment rather than as a replacement, and that claims to treat serious conditions warrant scepticism[1]. That is the right framing here: cupping may well help your stiff back, and should not be your primary approach to a diagnosed condition.
What a session involves
In UK practice, cupping is usually part of a longer appointment with a massage therapist, acupuncturist or tui na practitioner rather than a standalone booking.
The practitioner takes a health history, paying particular attention to medication, bleeding disorders and skin condition. You undress to expose the area, typically the back and shoulders. Cups are applied, suction is drawn, and you will feel a strong pulling sensation. Static cups stay in place for five to fifteen minutes; gliding cups are moved over oiled skin.
Expect the practitioner to check on you regularly, since suction should be reduced if it becomes uncomfortable. Afterwards the marks appear within minutes.
Prices are typically £30 to £60 as a standalone or £15 to £25 added to a massage. Comparative pricing is in how much a massage costs in the UK.
Safety and who should avoid it
Avoid cupping, or check with your GP first, if you:
- Take blood-thinning medication such as warfarin, apixaban or rivaroxaban
- Have a bleeding disorder such as haemophilia
- Have fragile, thin or easily damaged skin, including from long-term steroid use
- Have eczema, psoriasis, sunburn or a skin infection over the area
- Have deep vein thrombosis or symptoms of it
- Are pregnant, where the abdomen and lower back are avoided entirely
- Have severe anaemia
- Have a pacemaker, where cups are kept away from the device
- Have cancer, without oncology approval
Additional caution applies to wet cupping, which breaks the skin and therefore carries infection and bloodborne virus risk. Only consider it from a practitioner using sterile single-use equipment who is registered with their local authority for skin piercing.
