Face swelling due to trauma is mainly caused by the rupture of subcutaneous cells after the face is stimulated and struck by the outside world, and the swelling is caused by the accumulation of cellular contents under the skin. If you want to reduce the swelling, it is recommended to first use cold towel ice packs to prevent the cells from continuing to rupture and increase the elasticity of the cell walls, and choose to use hot towel heat packs, which can effectively promote the absorption of the cellular fluid accumulated under the skin by its own metabolism, so as to achieve the purpose of repair. If the face is accompanied by obvious pain while using ice packs, you can apply local lidocaine gel to relieve the pain, or you can choose to take the oral drug horse chestnut seed extract, which can effectively promote the vascular permeability of the whole body and accelerate the decreasing of swelling, so as to achieve the purpose of supplementary treatment. You can massage the swollen area more often to promote blood circulation, the effect is also good.
