Vacuum therapy is an aesthetic treatment that uses controlled suction application, generating negative pressure on the skin and underlying tissues, which leads to increased blood and lymphatic flow. This suction acts as a mechanical stimulus on the blood vessels and the lymphatic system, triggering physiological responses that include the dilation of blood vessels and increased blood flow, as well as stimulation and lymphatic drainage. These effects contribute to improving circulation, tissue oxygenation, toxin elimination, and relief of fluid retention.
