Blackheads: also known as blackheads acne, belong to the keratin embolism within the pores. As the sebum inside the pore is directly exposed, it becomes black due to oxidation in contact with air and dust. 2. Normal hair follicle tissue: As there are many hair follicles distributed at the root of the nose, nose, etc., the small black vellus hairs may be normal hair follicles growing out of the hairs, which is a normal phenomenon. If it affects aesthetics, it can be gently plucked after sterilization, but there can be some risk of infection. 3. Pigmented nevus: If a small pigmented nevus is present, it may also resemble a blackhead, but usually has an inconspicuous bump or no bump. Some pigmented nevi can also have hair growth, and it is recommended to remove them through laser treatment or other means. 4. Keratosis Pilaris: It mostly shows brown or black keratinized papules, which are commonly found in seborrheic areas of the skin. If follicular keratinization occurs in and around the nose, there may also be dark-colored bumps, similar to blackheads. 5. Hair follicle infection: the pores on the nose secrete oil exuberantly, such as the use of irritating skin care products, pore clogging, etc., may cause the surrounding hair follicles to become infected, appearing black in color and so on.
