Negative pressure therapy applies gentle, controlled suction to a wound through a specialised dressing connected to a small pump.
It’s generally considered for wounds under higher mechanical stress, and where used is typically initiated in a hospital or specialist wound setting.
The suction may help reduce swelling, support blood flow, and draw away fluid that could otherwise collect beneath the skin.
By supporting a more stable healing environment and reducing tension at the wound edges, it may also lower the risk of a widened or raised scar, since tension is one of the factors influencing how a scar forms.
It isn’t required for every wound. Its use is guided by wound location, tension and clinical judgement case by case.
If you’re managing a wound, or a scar that has resulted from one, get in touch to arrange a consultation if appropriate.
All procedures carry risks. Suitability for treatment requires individual clinical assessment. Individual outcomes vary.
