carbonic acid application shows rapid circulation response in cold-sensitive hands and feet
Carboxytherapy treatment of vascular acrosyndromes (acrocyanosis and Raynaud's phenomenon) produced benefit from the first session in 80% of patients, with no adverse effects reported.
What this means for you
Poor circulation in the hands and feet can cause persistent coldness, color changes, and discomfort that disrupts daily life. When carbonic acid is absorbed through the skin, it signals blood vessels to dilate — and in studies of people with these circulation patterns, 80% noticed a meaningful difference after just one session, with no adverse effects reported.
