Acne in Teenagers – The Facts

WHAT IS ACNE?

Acne vulgaris, consists of the non-inflammatory form, known as comedones & the inflammatory form. The inflammatory form is caused by bacterial infection of the comedones (commonly known as black head & white heads). Comedones are formed by a combination of the dead skin cells with sebum, which block the pores of the skin. Sebum is produced by the oil glands of the skin to moisturize the skin & hair.

Acne rates increase with increased sebum production. The bacteria, Propionibacterium acnes, is normally present on the skin and causes inflammation when it invades on the rich substrate of the comedones. The redness & swelling are due to inflammatory responses from the body to fight the infection. Infection & inflammation ranges from mild to severe.

AT WHAT AGE CAN IT START? IS IT VERY COMMON?

Acne can start at any age. It tends to occur when there is increase sebum production.

Sebum production can increase with heat, hormonal changes, genetic factors, medication, such as cortisols. About 80% of people develop acne at some point between 12-25 years old.

The increase of hormones during puberty causes increase sebum production, which causes higher rates of acne in teenagers. Some people have acne during pregnancy & menstruation due to the hormonal changes resulting to higher sebum production.

IS IT HEREDITARY?

Higher rates of sebum production can be hereditary, these individuals tend to have oily skin & are prone to having acne.

HOW CAN MY TEENAGER AVOID DEVELOPING ACNE?

Puberty is a challenging phase. While the hormonal changes cannot be avoided, there are other steps to reduce developing acne. Simple face washing & not picking at comedones help to reduce inflammation & bacterial infection. Avoiding oil based or comedogenic (pore blocking) facial products will help to reduce risk of blocking pores.

In addition to the above measures of preventing acne, medications are used to reduce the formation of comedones & treat infection or inflammation of the comedones.

Some to the treatment used include topical tretinoin, benzoyl peroxide, antibiotics, oral isotretinoin & hormonal treatment.
