The definition of complexion is appearance of the skin, especially on the face (its natural color, texture and quality). Some people have perfect complexion or glowing and even skin. However, the majority of the people have unhealthy skin tone and different skin imperfections.
Those who suffer from constipation have sallow skin tone and those that have some liver issues have yellow skin tone. People that discharge toxins all the time, have inflamed facial skin. The skin tone is genetic, but the way you live, the diet you practice and the skin hygiene are important factors that may improve the skin appearance.
The skin tone is related to the health condition of your body. If your organism is exhausted you won’t have a glowing skin and healthy look and vice versa. A healthy organism will reflect a healthy and glowing skin. The worst enemies of the skin are: overeating, excessive alcohol consumption, excessive cigarette smoking, not enough sleep, tiredness, anxiety, and excessive sun exposure.
