The debate between metronidazole and azelaic acid
Modern medical science, the research and refinement of drugs, metronidazole (Metronidazole) and azelaic acid (Azelaic Acid) are both useful in the field of healing, but compared with the two, each has its own short and long, and doctors often distinguish it in detail.

Metronidazole, its nature invades the bacterial cells, interferes with the metabolism of bacteria, and breaks the structure of its DNA, so it is effective against anaerobic bacteria and protozoa. For example, the disease of carbuncle is caused by anaerobic bacteria. With this drug, it can directly hit the disease center and make the bacteria inactive and slow down. However, it also has disadvantages. If it is taken, it may disturb the spleen and stomach, causing nausea and vomiting. If it is used for a long time, it will be resistant to bacteria, and the effect of the drug will gradually decrease.

Azelaic acid has the ability to resist bacteria, inhibit the proliferation of keratin, and regulate the secretion of oil. In the case of facial sores, it can clear the bacteria of the skin, smooth the thickness of hair follicles, reduce the spread of oil, and make the face smooth again. Its nature is mild, less sensitive to the skin, but the medicinal effect is slightly slower. In severe cases, it may not be effective when used alone.

If the common facial sores start at the beginning and the symptoms are not deep, azelaic acid may be the first choice, with its gentle skin care and gradual effect. The internal disease is caused by anaerobic bacteria, and the disease is urgent and serious. Metronidazole should be used as soon as possible to reduce the disease. However, the way of medication should not be rigid. It must be used in the patient's body, the severity of the disease, and the advantages and disadvantages of the drug, and the trade-off can be used to achieve the effect of rejuvenation. Doctors have verified the drug, so that metronidazole and azelaic acid are suitable for their respective uses, and few diseases are cured, and the people have no suffering.
