Acne (acne vulgaris) is a very common skin condition affecting adolescents.


Acne (acne vulgaris) is a very common skin condition affecting adolescents. Increased production of oil in the skin (sebum) and blocked sebaceous glands/pores cause pimples and blackheads that can become severely inflamed. Hormonal changes during puberty play an important role in the formation of acne. Mild acne can be treated at home with gentle skin cleansing lotions etc., but if the problem persists, a doctor should be consulted.
