Acne occurs most commonly during adolescence, and often continues into adulthood. In adolescence, acne is usually caused by an increase in testosterone, which accrues during puberty, regardless of sex. For most people, acne diminishes over time and tends to disappear, or at the very least decreases , by age 25.
Acne develops as a result of blockages in the follicles. Hyperkeratinization and formation of a plug of keratin and sebum is the earliest change. Enlargement of sebaceous glands and an increase in sebum production occur with increase androgen production.In these conditions, the naturally largely commensal ocurring bacterium Propionibacterium acnes can cause inflammation, leading to inflammatory lesions , like:papules, infected pustules, or nodules.
Many different treatments exist for acne including benzoyl peroxide, antibiotics, retinoids, antiseborrheic medications, anti-androgen medications, hormonal treatments, salicylic acid,alpha hydroxy acid, azelaic acid, nicotinamide, and keratolytic soaps. All this chemical treatments have a lot of side effects.
