First, a dark face caused by kidney deficiency. In Traditional Chinese Medicine, the kidney is considered the "water organ." When kidney yang is deficient, it leads to abnormal metabolism of fluids in the body. As these fluids overflow upward to the face, symptoms of a darkened complexion appear. People in this category often have a dull, lusterless face, accompanied by soreness and weakness in the lower back and knees, fatigue, cold hands and feet, decreased physical function, and low libido. In such cases, it is necessary to warm and tonify kidney yang; Yougui Wan can be used as a reference.

Second, a yellow face caused by spleen deficiency. TCM believes the spleen is the source of qi and blood production. When the spleen is weak, the production of qi and blood is affected, making one prone to symptoms of qi and blood deficiency. These include a yellowish, dull, and lusterless complexion, frequent dizziness, indigestion, and a heavy sensation in the body. At this time, it is necessary to tonify the spleen; Renshen Jianpi Wan can be used as a reference to strengthen the spleen, replenish qi, nourish the blood, and calm the mind.

The third is lung deficiency leading to a pale complexion. Traditional Chinese Medicine believes that a whitening of the face is mostly a manifestation of deficient lung Qi. Such individuals lack color in their faces, appearing very pale; they also tend to sweat easily with minimal exertion, feel short of breath and disinclined to speak, and frequently catch colds during seasonal changes. This condition is mostly due to lung Qi deficiency and requires nourishing the lung Qi; Shengmai Yin can be used as a reference.

A reminder to everyone: Traditional Chinese Medicine requires syndrome differentiation. If needed, please consult a professional physician for timely diagnosis, treatment, and conditioning.
