Acne, medically known as acne vulgaris, is associated with excessive secretion of sebaceous glands, consumption of spicy and stimulating foods, or staying up late. It also has links to individual familial genetics and hormonal imbalances. The main mechanism of the disease involves the sebaceous glands during secretion combining with Propionibacterium acnes on the skin surface, resulting in a purulent infectious disease. Once acne occurs, it is essential to seek proper treatment and avoid squeezing, picking, or forcibly removing with acne needles. Otherwise, it can lead to scarring or acne marks, which may affect one’s facial appearance later on.
