The skin contains oil producing glands known as sebaceous glands. These glands produce sebum (natural oil). Due to overproduction of sebum, the hair follicles in the skin get blocked with the oil and dead skin cells. As a result the oil and dead skin gets trapped in the hair follicles giving rise to a spot which is known as acne. In some cases, the normal microflora of the skin can also cause inflammation of the skin causing development of acne. It is not an infectious condition, and therefore does not spread by contact. Although the anaerobic bacterium known as Propionibacterium acnes has been found to activate the proinflammatory mediators at the follicular walls causing an inflammatory type of acne .
The prognosis of the condition is generally good and with appropriate medications it should generally fade off within some years. However, in certain cases, the acne may continue to go on for several years together.

Acne vulgaris is diagnosed using the grading scale system. Here, the lesions are compared with standard photographs for determining the grade of the condition.
Acne is categorized into 3 categories namely: mild, moderate and severe acne. Individuals with <20 comedones and< 15 inflammatory lesions are known to have developed mild acne. Those with 20 to 100 comedones and 15 to 50 inflammatory lesions are known to have developed moderate acne. Severe acne is described as having > 5 pseudocysts, total comedones greater than 100 and inflammatory lesions beyond 50.
Severe and persistent acne with a high rate of suspicion for a secondary gram negative bacterial infection may warrant culture and sensitivity tests .
Treatment of acne vulgaris depends on extent of severity of the disease and age of the individual. Various medications exist for treating this skin disorder. These include oral medications and topical creams and ointments to be applied on the affected area.
Medications that include benzoyl peroxide, antibiotics, hormones, salicyclic acid and retinols are administered. Benzoyl peroxide usually forms the primary line of treatment which causes the skin to shed its layer of dead skin . Oral antibiotics are given to treat infections, if they are the source of acne vulgaris development. Contraceptives are given if antibiotics do not work. These are method of choice when hormonal imbalance is the cause of acne breakouts.
In case of severe acne, retinoids are the treatment regime . Such medications work by reducing the sebum production of the sebaceous glands of the skin.
Keeping skin clean and free from excess of oil can help to a great extent in preventing acne breakouts. The skin should be washed at least twice in a day with a mild, fragrance free soap. Individuals should remember not to use to harsh scrubs for removing dead skin.
Acne vulgaris is defined as the development of spot along with pimples, papules, nodules and comedones on the skin. It is a major condition affecting millions of teenagers across the globe. With advancing age, acne disappears but may leave behind permanent scars which are a great cause of depression, anxiety and low self esteem amongst individuals.

Acne usually develops in conjugation with comedones, papules and pustules. The area is painful and tender to touch. Inflammation may also be noticed along with reddish scaly skin. Face is the most common area for development of acne.
The acne is compared with the standard pictures and diagnosis is made accordingly. There are three grades of acne which are dependent on the number of comedones and inflammatory lesions.
Treatment of acne vulgaris is directed towards treating the cause of the condition. In case of increased production of sebaceous glands, oral administration of medications containing retinoids is given that work by reducing the oil production. Oral antibiotics are given to reduce infection if they are the source of acne breakout. In addition to oral medications, topical ointments and creams are given to be applied on the affected area.
