How is Severe Acne Formed?

The initial pathogenesis behind severe acne is similar to other types of acne, viz, hormone stimulation of the sebaceous glands, thickening of the follicular wall and blockage of the hair pores.

In severe acne, the resident bacteria of the hair follicle, P.acnes, multiplies in the medium of the sebum causing breakdown of its components. This causes a chemical irritation, attracting inflammatory white blood cells known as neutrophils.

Neutrophils release some chemical mediators and enzymes which cause the typical characteristics of an inflammatory reaction within the sebaceous glands and the associated hair follicles: calor, rubor, dolor, tumor and functio-lesa, meaning: heat, redness, pain, swelling and loss of function of the affected area.

The inflammation and the resultant destruction of the follicular walls, sebaceous glands and the debris from the inflammatory reaction results in formation of pus filled bumps known as pustules.
