It is recommended to keep your face clean and wash your face with sulfur soap.
You can use an acne needle, which is a good product for removing acne and blackheads. After disinfection with alcohol, the stainless steel needle tip pierces the affected area, and then the steel ring is pressed down at the acne, which can immediately squeeze out the dirt.
After squeezing with acne needle, you can wipe the affected area with chloramphenicol.
