Whiteheads are a type of acne that appear as small, white bumps on the skin. They form when hair follicles become clogged with oil, dead skin cells, and bacteria. Unlike blackheads, which are open to the air and turn dark, whiteheads remain closed and look like tiny white or flesh-colored spots. They are most commonly found on the face, neck, and back. To treat whiteheads, it's important to keep the skin clean and use products that help unclog pores. Over-the-counter treatments containing ingredients like salicylic acid or benzoyl peroxide can be effective. Regular exfoliation and a good skincare routine can also help prevent their formation.
