is divided into three main types. Each of these types can further be classified
based on severity into mild, moderate, or severe. The severity is often based
on the number of lesions present as well as the presence of persistence, scarring,
and psychological impact.
This type of acne is the initial phase of acne and usually starts
with the onset of puberty. It initally appears on the nose and can progress to
involve the forehead, cheeks, and chin. This type of acne consists of black heads
and white heads, without the presence of pimples. Comedonal acne may exist separately
or with other types of acne.
This type of acne is the most common type of acne. It involves reddish
pimples and can range from mild to severe. It is most common on the face but also
commonly involves the neck, chest, back, and upper arms.
This type of acne is more severe than the papulopustular type and
involved the presence of large, deep lesions (nodules) as well as the formation
of acne cysts. This type can effect the face, back and chest and most commonly
is important to note, that most people will have a combination of the above types.
It is however important to identify the main component of the acne, as this will
help to decide the most appropriate treatments.
