What is Acne?

Acne is one of the most common skin conditions affecting both teenagers and adults. It develops when hair follicles become clogged with sebum and dead skin cells, leading to blackheads, pimples and sometimes deep, painful cysts. At MED-CLINIC, we see clients daily who struggle with this frustrating skin condition.

Acne vulgaris, the medical term for common acne, is a chronic inflammatory skin disease that affects the pilosebaceous units of the skin. The development of acne is a complex process that begins with increased sebum production by the sebaceous glands, often triggered by hormonal changes. Simultaneously, the hair follicle becomes blocked by a build-up of dead skin cells. This combination creates an ideal environment for the bacterium Cutibacterium acnes, which naturally lives on the skin.

When this bacterium multiplies in the blocked pore, it activates the immune system, leading to inflammation. This manifests as redness, swelling and pus — the characteristic signs of a spot. In severe acne, this inflammation can reach deeper into the skin, causing painful nodules and cysts that can leave scars.

It's important to understand that acne is not a hygiene problem. Excessive washing can actually irritate the skin and worsen symptoms. Acne is a medical condition that deserves professional treatment.

"Acne is much more than a cosmetic problem — it can have an enormous impact on self-confidence and quality of life. At MED-CLINIC, we don't just treat the symptoms, we address the underlying causes for lasting results."

The Science Behind Acne

The pathophysiology of acne involves four key factors that together contribute to the development of lesions. Firstly, hyperkeratinisation — an abnormal cornification of the cells lining the hair follicles. Secondly, seborrhoea plays a crucial role — the overproduction of sebum by the sebaceous glands under the influence of androgens. The third factor is bacterial colonisation by Cutibacterium acnes. Finally, inflammation plays a central role as the immune system responds to the bacterial activity.

Causes & Symptoms of Acne

Causes

  • 1. Excessive sebum production due to hormonal fluctuations
  • 2. Blocked pores from build-up of dead skin cells
  • 3. Bacterial growth (Cutibacterium acnes) in blocked follicles
  • 4. Hormonal changes during puberty, menstruation or pregnancy
  • 5. Genetic predisposition — acne often runs in families
  • 6. Certain medications such as corticosteroids and lithium
  • 7. Stress disrupting hormonal balance
  • 8. Use of comedogenic cosmetics or skincare products

Symptoms

  • Blackheads (open comedones) and whiteheads (closed comedones)
  • Papules — small red, inflamed bumps
  • Pustules — spots with visible white or yellow pus
  • Nodules — large, deep, painful lumps beneath the skin
  • Cysts — large, pus-filled swellings that can cause scarring
  • Oily skin, especially in the T-zone
  • Redness and inflammation around lesions
  • Post-inflammatory hyperpigmentation (dark spots after healing)

Risk Factors

Age — teenagers and young adults are at highest risk

Family history of acne

Hormonal conditions such as PCOS

Use of greasy or oily cosmetics

Regular friction on the skin (helmets, phones, face masks)

High stress levels

Certain dietary factors (dairy, high-glycaemic foods)

Working in humid or oily environments

Prevention Tips for Acne

Cleanse your face twice daily with a gentle, pH-balanced cleanser

Always use non-comedogenic skincare and makeup products

Avoid touching your face — hands carry bacteria

Change pillowcases regularly (every 2-3 days)

Use SPF50 daily — many acne treatments increase sun sensitivity

Manage stress through exercise, meditation or yoga

Avoid picking or squeezing spots — this causes scarring

Keep your phone screen clean — it touches your face daily

Lifestyle Advice

In addition to professional treatments, these lifestyle adjustments can help manage acne:

Maintain a consistent skincare routine — morning and evening

Exercise regularly to improve blood circulation and reduce stress

Get adequate sleep (7-9 hours) for skin repair and renewal

Stay hydrated — aim for 2 litres of water daily

Reduce dairy and high-sugar foods which can trigger breakouts

Clean makeup brushes weekly to prevent bacterial build-up

Myths vs Facts about Acne

Myth

Acne is caused by poor hygiene

Fact

Acne is a hormonal and inflammatory condition. Over-washing can actually make it worse.

Sun exposure clears acne

Sun may temporarily mask redness but can worsen acne long-term and cause hyperpigmentation.

Only teenagers get acne

Adult acne is very common, especially in women aged 25-45 due to hormonal fluctuations.

You should let acne 'run its course'

Early treatment prevents scarring and psychological impact. Professional help makes a significant difference.

When to Seek Professional Help?

It's important to consult a specialist in time. Book an appointment if you recognise one or more of the following situations:

  • Your acne doesn't respond to over-the-counter products after 8 weeks
  • You develop painful cysts or nodules deep under the skin
  • Acne leaves scars or dark marks on your skin
  • Acne significantly affects your self-confidence or mental wellbeing
  • You suspect hormonal acne (breakouts around jaw, chin, before periods)

Frequently Asked Questions about Acne

Find answers to the most common questions about acne. Have another question? Feel free to contact us.

What is the best treatment for acne?

This depends on the type and severity. For mild acne, HydraFacial and chemical peels work well. For moderate to severe acne, a combination of LED therapy, professional peels and targeted homecare is most effective.

How long before I see results?

Most clients notice improvement within 4-6 weeks with consistent treatment and homecare. Complete clearance typically takes 3-6 months.

Can acne come back after treatment?

Acne can recur, especially with hormonal triggers. That's why we create a maintenance plan including homecare to keep your skin clear long-term.

Is acne treatment safe during pregnancy?

Some treatments and ingredients are not suitable during pregnancy. We always discuss this during your consultation and adjust your plan accordingly.

Does diet affect acne?

Research shows links between high-glycaemic foods, dairy and acne. While diet alone doesn't cause acne, it can be a contributing factor.

Should I moisturise if I have oily, acne-prone skin?

Yes! Skipping moisturiser can actually increase oil production. Choose a lightweight, non-comedogenic moisturiser.
