What is the most effective way to remove closed comedones (closed acne) on the face?
Generally speaking, there is no single "most effective method" for removing closed comedones on the face. Closed comedones are a type of acne caused by clogged hair follicles and excessive sebum production. They can be categorized into microcomedones, whiteheads, and blackheads. Improvement can be achieved through treatments such as chemical peels (using alpha hydroxy acids), needle extraction, microneedling, photorejuvenation (intense pulsed light), and fractional laser therapy.
