What is Acne?

Acne, also known as Acne vulgaris is a chronic skin disease which involves inflammation of pilosebaceous units. It is the most common skin disorder during puberty, when the sebaceous gland activates, though it affects people of all ages. Classification of Acne into two categories:

  • Non-inflammatory Acne – Comedones
  • Inflammatory Acne – Pustules, Papules, Nodules, Cysts

Symptoms of Acne

Acne primarily appears on the skin as:

  • Blackheads (open comedones)
  • Whiteheads (closed comedones)
  • Red bumps (papules)

  • Deep pimples and boils (cysts).

Acne especially appears on the areas of the skin with a relatively high number of sebaceous glands like face, neck, shoulders, back, upper arms.

Causes of Acne

In almost 80 percent of the cases, genetics is thought to be the primary cause of Acne. In both sexes androgen hormones are responsible for the increased production of sebum, thus appear to be a significant player in the underlying mechanism.
