Approximately 70-95% of young people suffer from acne vulgaris during puberty. The skin produces too much sebum, and as a result, the pores become blocked. Whiteheads and blackheads can form. In this type of acne there are basically three characteristics to differentiate between:
Acne comedonica is the mildest form and is distinguished by the formation of open and closed comedones.
The medium-severe form, acne papulopustulosa, penetrates the deeper layers of the skin with its irritated spots and, in some cases, inflammations.
Acne conglobata is the severest form of acne vulgaris – this presents lumps, abscesses and pustules that can result in noticeable scarring.
Acne vulgaris usually disappears once puberty is over. If acne occurs after you’ve turned 25, it is known as late onset acne.
This chronic type of acne occurs in phases. The symptoms are more severe and can be seen in more areas of the body such as the shoulders or groin. In this type, small lumps form under the skin that can develop into abscesses or pustules.
Small spots can form on the skin a few days after having been exposed to intense sun radiation. Such skin reactions occur due to UV rays resulting in inflammation in the hair follicles and causes itchiness.
