There are many reasons for a yellowish face, which are described below from three perspectives: physiology, environment and diet.

Physiologically, yellowing of the face may be caused by liver dysfunction. Liver is the main excretory organ of metabolic wastes in human body, if liver function is not good, it will lead to the accumulation of toxins in the body, the blood contains too many toxins and wastes, these substances will be expressed through the skin, so that the skin will become dark yellow or dull.

Environmentally, exposure to pollutants in daily life may also lead to a yellowish face. For example, air pollution, ultraviolet radiation, and electromagnetic radiation may affect the skin's metabolism and respiration, increasing skin pigmentation and oxidative reactions, making the skin yellowish.

Diet, long-term high-fat, high-sugar diet or lack of vitamin C and other nutrients may also lead to yellowish face. These nutrients play an important role in the body's circulatory and immune systems, and a lack of these elements can affect blood circulation and metabolism, resulting in poorer skin quality and dull color.

For the problem of yellow face, we can start from the following aspects to improve:

Diet should pay attention to the balanced nutrition, especially eat more fruits and vegetables to intake of enough vitamin C, to help discharge the body's toxins, promote metabolism.

2. Pay attention to protect your skin from pollutants and prolonged exposure to ultraviolet light. You can choose to wear protective items such as masks, hats and sunglasses.

3. Exercise to enhance body immunity and tolerance. Moderate aerobic exercise can promote blood circulation throughout the body and enhance metabolic function, which is beneficial to discharging toxins and wastes in the body.

4. Sleep well. A lack of sleep can affect the body's metabolism and recovery ability, resulting in dull, yellow skin. A regular schedule can help improve this problem.

Finally, we recommend a skincare product - Warmth and Brightness Essentials, which is a favorite product of many consumers because of its effectiveness in improving the skin's dullness. However, before using any skincare product, you should pay attention to your skin type and allergies to avoid aggravating skin problems due to improper use.
