Evidence based
BLOOM⁴³ delivers ultra-precise Supraphysiological Preconditioning™ to boost blood flow and prime the skin, helping lower the risk of post-op complications such as skin necrosis.
Using a sensor-controlled, patented, intermittent thermal algorithm, BLOOM⁴³ triggers the release of protective Heat Shock Proteins (HSPs), including HSP-32, which induces the release of carbon monoxide in the local tissue- a powerful vasodilator and increases blood flow to the area.
Better blood flow means better healing.
