Chinese medicine believes that the blockage of meridians leads to stagnation of blood stasis, which prevents blood from reaching the skin and face and nourishing the skin, while metabolic wastes, harmful substances and melanin in the skin cannot be excreted with the normal metabolism of the human body, which is what Chinese medicine calls facial plaque accumulation. Where there are spots, there must be stasis, and where there are spots, there must be stasis. The reason why pigmentation is difficult to be cured is that ordinary drugs can not directly penetrate into the focus, and it is difficult to completely remove pus attached to meridians like bean curd residue. Most patients with pigmentation have symptoms of deficiency of both qi and blood to some extent.

Liver, spleen and kidney are most likely to affect skin color; There are several spots. If there are liver spots, spleen spots, kidney spots and internal modulation, it is necessary to prescribe the right medicine. Everyone's physique is different, so it's best to eat internal medicine under the guidance of a doctor.
