carbonic acid skin exposure increases blood flow and oxygen delivery to the lower limbs
Transcutaneous CO2 application produced vasomotor effects in patients with stage II peripheral occlusive arterial disease.
What this means for you
When CO₂ absorbs through the skin, blood vessels in the legs and feet respond by opening wider — a process called vasodilation. This means more oxygen-rich blood reaches areas that often feel cold, heavy, or slow to recover. For people focused on circulation, leg comfort, and peripheral wellness, that kind of vascular response is worth paying attention to.
