Acne vulgaris
Acne is a chronic, inflammatory skin condition that causes spots and pimples, especially on the face, shoulders, back, neck, chest, and upper arms.
Acne is most common in girls from the ages of 14 to 17, and in boys from the ages of 16 to 19 “puberty age” • Acne most commonly develops on the: • face – this affects almost everyone with acne • back – this affects more than half of people with acne • chest – this affects about 15% of people with acne
Types of spots
There are 6 main types of spot caused by acne:
blackheads – small black or yellowish bumps that develop on the
skin; they're not filled with dirt, but are black because the inner lining
of the hair follicle produces pigmentation (coloring)
whiteheads – have a similar appearance to blackheads, but may be
firmer and won't empty when squeezed
papules – small red bumps that may feel tender or sore
pustules – similar to papules, but have a white tip in the center,
caused by a build-up of pus
nodules – large hard lumps that build up beneath the surface of the
skin and can be painful
Cysts – the most severe type of spot caused by acne; they're large pus-
filled lumps that look similar to boils and carry the greatest risk of
causing permanent scarring.
Risk factors include genetics, the menstrual cycle, anxiety and stress, hot and humid climates, using oil-based makeup, and squeezing pimples.
Diagnosis How severe your acne is will determine where you should go for
treatment and what treatment you should have.
The severity of acne is often categorized as:
Mild – mostly whiteheads and blackheads, with a few papules and
pustules.
Moderate – more widespread whiteheads and blackheads, with
many papules and pustules.
Severe – lots of large, painful papules, pustules, nodules or cysts;
you might also have some scarring.
Acne in women If acne suddenly starts in adult women, it can be a sign of a
hormonal imbalance, especially if it's accompanied by other
symptoms such as:
Excessive body hair (hirsutism).
Irregular or light periods.
The most common cause of hormonal imbalances in women
is polycystic ovary syndrome (PCOS).
PCOS can be diagnosed using a combination of ultrasound
scans and blood tests.
The approach to acne management is largely determined by:
• Severity index. • Lesion type: predominantly non inflammatory or inflammatory. • Treatment preferences including patient choices. • Cost implications. • Skin type and/or ethnic group. • Patient age. • Adherence. • Response to previous therapy. • Presence of scarring. • Psychologic effects. • Family history of persistent acne.
Non pharmacological Diet: It is unclear what role diet plays in worsening acne. Scientists have
found that people who consume a diet that offers a good supply
of vitamins A and E and of zinc may have a lower risk of severe acne.
But suggests that a diet with a low glycemic load may help.
Tea-tree oil: may help treat mild to moderate acne.
Tea: There is some evidence that polyphenols from tea, including green
tea, applied in a topical preparation, may be beneficial in reducing sebum
production and treating acne. However, the compounds in this case were
extracted from tea, rather than using tea directly.
Moisturizers: These can soothe the skin, especially in people who are
using acne treatment such as isotretinoin, say researchers. Moisturizers
containing aloe vera at a concentration of at least 10 percent or witch
hazel can have a soothing and possibly anti-inflammatory effect.
Desired Outcomes (Goals of Treatment)
Basic goals of treatment include alleviation of symptoms by reducing the
number and severity of lesions and improving appearance, slowing
progression, limiting duration and recurrence, prevention of long-term
disfigurement associated with scarring and hyperpigmentation, and
avoidance of psychologic suffering.
Treatment for acne depends on how severe it is. It can take several
months of treatment before acne symptoms improve.
