Kidney Yang deficiency does not usually cause chloasma on the face. Chloasma belongs to the category of “sallow spot”, “black spot” and “face dust” in Chinese medicine. According to Chinese medicine, chloasma is always caused by poor qi (poor operation of human body gases), wind in the coupling, anxiety and depression, and dysfunction of liver, spleen and kidneys. The pathogenesis of chloasma is liver depression and qi stagnation (poor qi and blood transportation of the liver, emotional depression), qi stagnation and blood stasis (blood stagnation because of the lack of qi flow), spleen and stomach weakness, and liver and kidney insufficiency (weakness of the liver and kidneys). Kidney-Yang deficiency, i.e., deficiency and failure of yang energy in the kidneys, is commonly caused by kidney deficiency in old age and yang deficiency in the vegetative system. People with kidney yang deficiency will have symptoms such as pale face, slightly cold limbs, clear and long urination, weakness of limbs, spermatorrhea in men and irregular menstruation in women. If the symptoms of sallow spots on the face appear, it can be treated with medicines such as detoxification capsule, Jia Wei Yi San, and Safflower Easy Tablet. It is necessary to consult a doctor to identify the evidence and use medication, after the guidance of Chinese medicine practitioners to identify the evidence for treatment, do not blindly treat yourself, so as to avoid delays in the condition.
