How to improve dull, yellowish skin lacking luster
Generally, dull and yellowish skin without luster may be caused by factors such as aging, unhealthy lifestyle habits, spleen and stomach weakness, anemia, and endocrine disorders. Treatment or relief can be achieved through general therapy, medication, and other methods depending on the specific situation. It is recommended to seek timely medical advice to determine the underlying cause and undergo appropriate treatment under a doctor's guidance. A detailed analysis is as follows:

1. Aging: With age, the skin's metabolic rate slows down and the stratum corneum thickens, which affects the skin's transparency, making it appear dull and yellowish. Regular gentle exfoliation treatments and skincare products containing ingredients such as vitamin C and hyaluronic acid are recommended.
2. Unhealthy lifestyle habits: Poor lifestyle habits can affect the body's endocrine system and metabolism, preventing the skin from receiving adequate nutrition and rest, thereby appearing dull and lacking luster, possibly accompanied by symptoms such as fatigue and weakness. It is recommended to maintain a regular sleep schedule and ensure 7-8 hours of high-quality sleep daily.
3. Spleen and Stomach Weakness: Weakness of the spleen and stomach can lead to insufficient qi and blood, preventing the skin from receiving adequate nourishment and moisture, resulting in dull, yellowish skin, possibly accompanied by symptoms such as poor appetite and abdominal distension. Patients may use medications such as Shenling Baizhu Powder, Xiangsha Yangwei Pills, and Fuzi Lizhong Pills under a doctor's guidance.
4. Anemia: The main cause is insufficient or reduced red blood cell production, leading to tissue hypoxia in the skin, causing the skin to lose its rosy luster and appear dull and yellowish, often accompanied by symptoms such as fatigue and palpitations. Patients may use medications such as ferrous sulfate sustained-release tablets, iron fumarate tablets, and polysaccharide iron complex capsules under a doctor's guidance.
5. Endocrine disorders: This may be related to imbalanced nutrition, anxiety, etc., which affects metabolism, causing dry, yellowish skin, possibly accompanied by symptoms such as palpitations and excessive sweating. Patients may use medications such as Jiawei Xiaoyao Pills, Qizhi Xiangfu Pills, and Wujibai Feng Pills as directed by a physician.
In daily diet, it is advisable to consume foods rich in vitamins and minerals while avoiding greasy and spicy foods.
