carbonic acid application increases local blood flow without lowering systemic blood pressure
CO2 vasodilatation is limited to areas of application, meaning local increase in blood flow occurs without a drop in systemic blood pressure and without a 'stealing' or 'borrowing-lending' effect, unlike pharmacologic vasodilators.
What this means for you
Most things that boost circulation in one area can pull blood away from others — or drop your overall blood pressure. CO2 applied to the skin appears to widen blood vessels only where it contacts the body, so targeted areas get more oxygen and nutrients without the lightheadedness or systemic side effects that can come with other approaches. That's a meaningful difference for people focused on recovery, circulation, or tissue support.
