According to your description, it should be acne and sores on the corners of the mouth caused by liver fire. From the perspective of traditional Chinese medicine, the liver is closely related to people's emotions. It is not clear whether the patient has symptoms such as irritability, insomnia and palpitation recently.

One more thing, when the liver dominates the eyes and the liver fire is strong, you often feel eye pain, your vision suddenly drops, you can't see clearly, and occasionally it is accompanied by tinnitus. When you go to the toilet, you will find that the urine is yellow, and at the same time you will be thirsty and often want to drink water.

In this case, we should first adjust our emotions, release the pressure appropriately and feel happy. If we eat and sleep normally, we will get better naturally. Then pay attention to a light diet, usually eat less fried food, fried chicken and chicken legs, barbecue, too spicy and other irritating foods. And foods that are too warm, such as mutton, to avoid adding oil to the fire and increasing the burden on the liver. The diet is mainly light, and foods rich in vitamins such as vegetables and fruits. Drink less drinks, especially carbonated drinks. There is also reasonable and appropriate exercise, the weather gets warmer, you can relax properly during the day or at night, and exercise can also adjust your irritability and depression.
