topical CO₂ application rapidly increases local blood flow and stimulates rhythmic vessel movement
External CO2 application to a small skin site produced increased blood flow reaching maximum within approximately 2–3 min and marked stimulation of rhythmical vasomotion with increased amplitudes, with effects strongly dependent on dose and temperature and ceasing rapidly upon CO2 withdrawal.
What this means for you
When blood flow rises quickly in skin tissue, more oxygen and nutrients reach that area — which can support faster recovery, a healthy glow, and the kind of circulation most people notice as warmth and reduced tension. The rhythmic vessel response suggests the vascular system is actively engaging, not just passively responding.
