What is closed comedones
Closed comedones, also known as whiteheads, are a common type of acne. It is mainly caused by the blockage of pilosebaceous gland ducts and appears as slightly convex white or skin-colored particles on the surface of the skin, usually without redness or pain. Unlike open comedones (blackheads), the pores of closed comedones are not exposed to the air, so they are less likely to oxidize and turn black.
