How does GFOUK Varicose Vein Relief Herbal Foot Patch works? The GFOUK Varicose Vein Relief Herbal Foot Patch contain a combination of natural ingredients, including herbs, minerals, and vitamins. Some of these ingredients may have anti-inflammatory or antioxidant properties, which could potentially help improve circulation and reduce inflammation in the veins. However, it is not clear how these ingredients would be able to penetrate the skin and affect the veins in the legs. A microclimate environment is generated between the skin and the patch when the patch is applied to the skin. This incredibly special environment promotes skin self-healing by retaining moisture, reducing varicose veins, and enabling blood to flow freely.
