What is Acne?

Acne is a common skin condition caused by clogged hair follicles due to excess oil, dead skin cells, and bacteria. It often appears on the face, chest, back, and shoulders, primarily affecting adolescents but also occurring in adults due to hormonal changes, stress, or other factors.

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 are the Symptoms?

Acne can present as blackheads, whiteheads, pimples, nodules, or cysts. Blackheads and whiteheads are non-inflammatory, while pimples, nodules, and cysts are inflamed, often painful, and may leave scars if untreated.

What are the Treatments?

Treatments vary based on severity. Over-the-counter products with benzoyl peroxide or salicylic acid can manage mild acne. Prescription treatments, such as topical retinoids, antibiotics, or hormonal therapy, may be necessary for moderate cases. Severe acne may require oral isotretinoin. Consistent skincare, avoiding harsh products, and consulting a dermatologist are crucial for effective management.

What is the Prognosis?

With proper treatment, most acne can be controlled or cleared, though it may take weeks to months for significant improvement. Early and consistent treatment reduces the risk of permanent scarring and helps maintain clearer skin over time.

FAQs about acne

Why do you get acne?

The cause of acne is complex. It is often a combination of hormonal changes, the skin changing i.e. becoming more oily, genetics and external factors like diet, smoking, drugs etc.

Can acne be contagious?

No, acne is not contagious. The bacterium that aggravates acne is normally found on everyone's skin however when the conditions are right it creates a gateway to infection and acne appears.

What can I do to prevent/reduce acne breakouts?

  1. Wash your face with soap and soap/cleansers that are gentle on the skin and have a pH of around 6.5.
  2. Use products with little oil/grease in them. Choose 'non-comedogenic' products where possible.
  3. Avoid touching your face and do not scratch and pick at acne.

If you have received local treatment from your doctor, it is important to apply this all over your face, and not just where there is an outbreak.

Is it dangerous to be on antibiotics for so long?

No. It is not dangerous, but Dermatologists have a responsibility to balance your needs (treatment) with antibiotic stewardship (to prevent development of resistance to antibiotics). As such, we don't typically suggest treatment lengths above and beyond three months.

I'm pregnant, can I still get treatment for acne?

Yes, but your options are limited. It is important to consult a doctor as even topical treatments may be harmful to your unborn child. Inform your doctor that you are pregnant before starting treatment so they can find the right treatment that is safe for both you and the child.
