What Causes Yellow Skin?
In daily life, we often observe that facial complexions vary significantly among individuals. Some people have especially healthy-looking skin—fair, tender, and rosy—while others appear sallow, dull, and lackluster. Since individuals differ in physical constitution, natural variations in skin tone are expected. However, a persistently sallow complexion is not always normal.

What Causes Yellowish Skin?
1. Sallow Complexion Due to Spleen Deficiency
A sallow or yellowish complexion often reflects spleen deficiency, leading to impaired circulation of Qi and blood. If both the face and urine appear yellow, this may indicate jaundice. Jaundice is further classified into “Yang Huang” (excess-type jaundice) and “Yin Huang” (deficiency-type jaundice): bright yellow discoloration suggests Yang Huang, caused by damp-heat accumulation; while a dull, smoky-yellow hue indicates Yin Huang, resulting from cold-damp stagnation. A yellowish, puffy appearance (“Huang Pang”) typically signifies spleen deficiency with impaired transportation and transformation, causing internal retention of fluids.
2. Sallow Complexion Due to Anemia or Qi-Blood Deficiency
A slightly yellowish or pale-yellow complexion is commonly attributable to Qi-blood deficiency. Individuals with weak digestive absorption may develop nutritional deficiencies as a result.
3. Sallow Complexion Due to Malnutrition
Many young women pursuing weight loss consume only fruits per meal, drastically reducing intake of staple foods and protein-rich foods such as meat—leading to a sallow, lackluster complexion.

4. Ultraviolet (UV) Radiation Exposure
UV radiation is a primary contributor to skin aging. It disrupts skin texture, impairs microcirculation, and promotes melanin deposition—resulting in a dull, yellowish complexion.
5. Chronic Sleep Deprivation and Late-Night Habits
Insufficient sleep due to habitual late-night activity deprives the liver and gallbladder of adequate rest, potentially manifesting as rough skin, hyperpigmented spots, and a sallow complexion.
6. Dietary Factors
Certain vegetables and fruits—including carrots, pumpkins, orange juice, water spinach (Ipomoea aquatica), kale, and mangoes—are rich in beta-carotene. Excessive consumption can lead to carotenemia, causing yellowish discoloration of the skin—most prominently on the palms and soles, followed by the face and postauricular areas; in severe cases, the entire body may be affected.

The above outlines the common causes of yellowish skin. We hope this information proves helpful.
