What cause bad skin

TCM takes a holistic approach to health. To be healthy, one’s qi (vital energy) and blood must flow freely throughout the body and its organs, maintaining a balance of yin (cooling) and yang (heating) elements. Because all of the body’s functions are interdependent, bad skin can be caused by a number of different types of imbalances.
One possibility is a malfunctioning metabolism, caused by the poor circulation of qi or blood. When your body fails to eliminate waste properly, those toxins will be expelled through your skin, causing acne.
Skin problems can also be a sign of inflammation arising from an excess of heat in the body. Excess heat in the lungs is a common culprit, as the lungs are responsible for providing the skin with blood and qi. If you have digestive problems, stomach heat could be the cause. Meanwhile, excess heat in the blood is accompanied by signs of inflammation throughout the body, such as rashes or sensations of heat.
The last cause of bad skin is “damp heat.” This occurs when dampness accumulates in the body and combines with heat, leading to symptoms such as oily skin, eczema and acne.
