Acne clearing needle, also known as needle clearing technique, refers to the timely release of inflammatory secretions in the follicular sebaceous glands by means of needle clearing acne, which reduces irritation, destroys the anaerobic environment of the follicular sebaceous glands and aids in the treatment of acne. This method is easy to operate, causes less inflammatory reaction, less pain, faster wound healing, easy for patients to accept, and relatively obvious therapeutic effects. Acne clearing needles help to accelerate the healing of acne while draining acne, and can also effectively inhibit acne growth. However, needle clearing is the most primitive method of acne removal, which is difficult to eradicate acne, prone to recurrence, and prone to infection. The effect of this operation is not permanent and varies according to individual circumstances. Generally speaking, acne clearing needles can only solve the current facial problem, and treatment is still needed when new acne problems appear on the face. The whole operation is not complicated, simple and quick. However, immature acne cannot be cleared by needles, otherwise it will easily spread, become infected, and cause pain. The main risks are local infection due to poor aseptic operation, aggravation of scar growth, hyperpigmentation, and transmission of infectious diseases (AIDS, syphilis, hepatitis, etc.), and bleeding. Therefore, patients should choose a regular plastic surgery institution with an experienced physician to perform standardized surgical operations, which can effectively prevent the occurrence of infection. In case of facial infection, treatment should be carried out promptly.
