How does carboxytherapy work for dark undereye circles?
One major cause of dark under eye circles is vascular pooling. The capillary network of the lower eyelids can become congested for a variety of reasons. Normally, the tears drain from the eyelids into the nose, but if there is some obstruction due to chronic nasal congestion from seasonal allergies, previous nasal fracture, or a deviated septum, the drainage doesn’t function well, and the blood flow to the lower eyelids becomes sluggish, giving rise to the boggy blue tinge known casually as “allergic shiners.” The lack of appropriate oxygenation to the lower eyelid skin allows the bluish cast to show through the thin skin of the eyelids. Carboxytherapy works to improve the capillary network of the lower eyelids, as well as to increase the dermal collagen layer in the lower eyelid skin. By injecting a small amount of carbon dioxide gas into the affected areas, blood flow is increased and improved capillary networks are formed for longer lasting circulatory benefit. The bluish cast is re
