Sebaceous grains on the face may be “milia”, which are tiny cysts formed by the retention of epithelial keratin in the epidermis or the ducts of hair follicles, sweat glands, and other skin appendages; they are benign lesions that usually have no self-conscious symptoms and do not require special treatment. If there is an aesthetic demand, physical therapy, needle picking and other methods can be taken. 1. Physical therapy: the treatment of cornu rashes is mainly based on physical therapy, which can use electrocautery, i.e., using high voltage, small current intensity of high-frequency power supply to burn and destroy the diseased tissues; or CO2 laser can be used to destroy the epidermis on the surface of the cornu rashes, and then pick out the white content with a sterile needle, or directly remove the entire cornu rashes. 2. Needle picking: Under the operation of professional doctors, the affected area can be sterilized with alcohol, and the surface of the papule can be picked with a sterile needle to squeeze out the milky white content. It is important to note that the wound needs to be kept dry and clean after the treatment of this disease. It is recommended that patients go to a regular hospital, under the guidance of the doctor to choose the appropriate treatment program, and follow the doctor’s instructions to receive treatment.
