Acne is categorized into whiteheads and blackheads, both of which belong to acne. Whiteheads are caused by a mixture of sebum and skin cells present in the pores, forming white particles with no openings on the surface of the skin, while blackheads are caused by a bolus of sebum and skin cells, with openings on the surface of the skin, and blackheads are caused by the sebaceous glands that darken and form blackheads when they are exposed to the air.
