It is estimated that around 80% of adolescents and young adults (aged 11-30) experience acne to some degree. Acne typically begins around the age of 12-14, and often even earlier in girls. Both genders are affected equally. Acne usually resolves by the 30s, but in some cases, it can persist longer.
What is acne?
Acne itself is a fairly simple concept. Humans have small sebaceous glands that lubricate the hair follicles with a natural oil called sebum. Too much of this, combined with dead skin cells, can clog a follicle. The clogged follicle can bulge out into a white dot, or develop into a blackhead. Normal skin bacteria can then spread, and you get a papule, a pustule or a nodule – basically an inflamed small infection. This is acne.
Types of acne
In general, acne is divided into four groups based on how severely it is affected: mild, moderate, moderate to severe and severe. Furthermore, acne can be categorized as comedonal acne, papulopustular acne, cystic acne or deep acne, depending on the form in which it occurs. Acne can, in addition to the physical effect, also have a strong psychological effect on people, and can therefore be associated with anxiety and depression.
