Blackheads and whiteheads are both types of comedonal acne but have distinct differences. Blackheads, or open comedones, form when a clogged pore remains open, exposing the contents to air and causing oxidation, which turns them black.
Whiteheads, or closed comedones, occur when a pore becomes clogged and remains closed, resulting in a white or flesh-colored bump. Both types can occur on the face, neck, shoulders, chest, and back. Treatment for both involves similar strategies, including topical retinoids, salicylic acid, and benzoyl peroxide, but recognizing the differences helps tailor specific skincare routines for effective management.
