What are black dots
Human skin is covered with a huge number of pores – 100 pieces per square centimeter. Through them, the sebaceous glands moisturize and protect the surface of the body. This is normal. But sometimes the pores are clogged with dead skin, dirt and dust, and the top is clogged with sebum. This is how comedones appear: closed (acne) and open (black dots). Most often this occurs in the places where the sebaceous glands are most active: on the face (nose, forehead, chin), back and neck.
