Acne is caused by the infection of Propionibacterium acnes. This condition is related to factors such as excessive sebum secretion of the skin, frequent consumption of spicy, greasy, and sweet foods, as well as regular late nights, anxiety, and stress. The disease is not contagious; it does not spread through contact with others, nor through sharing towels or bath scrubs. Once diagnosed, it is crucial to seek proper treatment to prevent the condition from worsening and potentially leading to scars or pits on the face. Treatment can be sought at a reputable hospital's dermatology department, where oral medication combined with topical treatments, and supplemented by phototherapy with red and blue light, can be effective. After recovery, it is important to regulate one's diet and lifestyle, avoid spicy and irritating foods, minimize staying up late, engage in exercise, bathe more frequently, and sweat more.
