1. The triangle cannot be squeezed by yourself, but needs to be squeezed under the guidance of a physician. The triangle formed by the root of the nose and the two corners of the mouth can easily lead to intracranial infection if bacteria are squeezed incorrectly. In addition, poor sterilization of squeezing tools (e.g., dirty hands) and a poor sense of innocuousness can lead to bacterial irritation, which can aggravate acne and even lead to new infectious diseases. Therefore, physicians caution that acne should not be self-squeezed and should be squeezed under the guidance of a physician.
2. If you have pustules, whiteheads or blackheads, you should gently squeeze them with a squeezer while the follicle opening is open and the sebaceous glands are softening. However, when pus has already formed, needle clearing can be done after strict disinfection. In the case of aggregated acne, when the pus is abscessed, the pus must be drained by incision or extracted with a large needle.
