What is acne? Causes, symptoms, and treatments explained

Acne is one of the most common skin conditions in the world, yet it can feel deeply personal and frustrating. Whether it appears on your face during your teenage years, lingers into adulthood, or shows up unexpectedly later in life, acne can impact your confidence, comfort, and overall skin health.

Studies show that up to 85% of people experience acne at some point in their lives. 

Although acne is commonly linked to teenagers, many adults also face breakouts, acne scars, and ongoing skin concerns. The good news is that, with the right knowledge and expert acne treatment, it can be effectively managed and even prevented.

In this blog, we’ll explain what is acne, what causes it, the symptoms, different types of acne, and the best acne treatments available today.

What is acne?

Acne is a skin condition that develops when hair follicles get clogged with oil (sebum), dead skin cells, and bacteria. This leads to spots, blackheads, whiteheads, and sometimes more severe lesions such as cysts or nodules.

While acne is most common on the face, it can also appear on the chest, back, and shoulders. People with acne-prone skin often notice frequent breakouts, oily skin, and visible pores.

What are the symptoms of acne?

Acne can appear in different ways. For some, it may be just a few occasional spots, while for others, it can be more widespread and persistent.

Common signs include:

  • Blackheads, whiteheads, small red bumps, or pus-filled spots
  • Areas of redness or swelling
  • Painful, deeper lumps under the skin in more severe cases

Possible longer-term effects:

  • Marks or scars that may look pitted, raised, or darker than the surrounding skin
  • Oily or uneven skin texture

Beyond the visible signs, acne can also damage self-confidence. Many people feel anxious or self-conscious about their skin, which is why seeking acne treatment early can make a big difference, not just for their complexion but also for their overall well-being.

What causes acne?

There isn’t one single reason why acne develops. Instead, it happens when a combination of factors affect the skin:

  • Excess oil production: Overactive sebaceous glands can block pores.
  • Build-up of dead skin cells: These can stick together with oil and clog follicles.
  • Bacteria growth: When trapped inside pores, it can lead to redness and swelling.
  • Hormonal changes: Shifts during puberty, monthly cycles, pregnancy, or even stress often make breakouts worse.
  • Genetics: If acne runs in your family, you may be more likely to experience it yourself.
  • Foods: Certain foods, such as dairy products, sugary foods and drinks, and fried and greasy foods, can cause acne in some people.

What are the types of acne?

Acne can appear in many different forms, ranging from mild spots to more severe breakouts. Understanding the type of acne can help you choose the right treatment.

  • Blackheads: Small dark spots caused by pores clogged with oil and dead skin. The pores remain open at the surface.
  • Whiteheads: Closed, clogged pores that appear as tiny white or flesh-coloured bumps.
  • Papules: Red, inflamed spots that can feel tender to the touch.
  • Pustules: Similar to papules but filled with pus, often showing a yellow or white tip.
  • Nodules: Large, firm, and painful lumps that develop deep under the skin.
  • Cystic acne: The most severe type, with pus-filled cysts beneath the skin. These can leave scars if untreated.
  • Hormonal acne: Breakouts linked to hormone changes, often appearing around the chin and jawline, especially during menstrual cycles or hormonal imbalances.
  • Fungal acne: Caused by yeast rather than bacteria, usually appearing as small, itchy bumps on the chest, back, or face.
  • Bacterial acne: Develops when bacteria grow in blocked pores, causing swelling, redness, and inflammation.

How is acne diagnosed?

The process of diagnosing acne is straightforward but very important for choosing the right treatment.

  • Skin evaluation: A dermatologist carefully examines your skin to assess the type and severity of acne.
  • Medical history: Your doctor may ask about hormonal changes, diet, lifestyle habits, or medications that could be contributing.
  • Tests (if required): In certain cases, such as suspected hormonal acne or fungal acne, blood tests or skin swabs may be recommended.

Getting a professional diagnosis helps you avoid guesswork and ensures you receive safe, effective acne treatment tailored to your needs.

What are the different options for acne treatment?

There isn’t a one-size-fits-all solution for acne. The best acne treatment depends on the type of acne, its severity, and how your skin responds.

1. Medical treatments

Dermatologists often begin with prescription medicines that directly target breakouts:

  • Topical treatments: creams or gels with retinoids, benzoyl peroxide, or antibiotics to clear blocked pores and reduce bacteria.
  • Oral medications: antibiotics to fight inflammation, hormonal therapy for hormone-related acne, and isotretinoin for severe or cystic acne.
2. Advanced aesthetic procedures

For more stubborn acne or acne scars, modern aesthetic treatments provide excellent results:

  • Chemical peels: exfoliate dead cells and improve skin texture.
  • Laser therapy: reduces bacteria and smooths scars.
  • Microneedling with PRP: stimulates collagen production and aids skin repair.
  • Light-based therapy: reduces inflammation and kills acne-causing bacteria.
  • Drainage and excision: small cysts or nodules can be safely drained or excised to relieve pain and prevent further infection.
  • Steroid injections: powerful anti-inflammatory injections can quickly reduce large, painful cysts and minimise the risk of scarring.
3. Lifestyle and skincare adjustments

Daily habits are just as important as clinical care:

  • Cleanse skin gently twice a day.
  • Use non-comedogenic skincare and makeup.
  • Stay hydrated and protect skin with sunscreen.
  • Avoid picking or squeezing spots to prevent scars.

Our dermatologists can help you build a personalised treatment plan combining medical, aesthetic, and lifestyle measures, giving you the best chance of clear, healthy skin.

What are acne scars?

Acne doesn’t always end when the spots fade. For some people, breakouts leave behind acne scars, ie, the marks that can be pitted, raised, or discoloured compared to the surrounding skin.

These scars form when inflammation from acne damages the deeper layers of skin during the healing process.

The different types of acne scars include:

  • Atrophic scars: shallow depressions in the skin (common on the face).
  • Hypertrophic scars: raised, thickened scars that form where the skin produces too much collagen.
  • Post-inflammatory hyperpigmentation: dark spots left after acne heals (not technically scars, but they can be just as distressing).

What is the best treatment for acne scars?

There isn’t a single best treatment for acne scars, because every scar type and every skin is different. The most effective approach is usually a personalised treatment plan created by our dermatologist.

Some of the options of treatment for acne scars include:

  • Laser resurfacing: considered one of the gold standards, it improves both texture and pigmentation by stimulating new collagen.
  • Microneedling with PRP: boosts skin healing and works well for pitted scars.
  • Chemical peels: gently remove damaged layers and refresh the skin.
  • Dermal fillers: instantly lift depressed scars for a smoother surface.
  • Topical treatments: retinoids, vitamin C, or specialised creams to fade pigmentation and support skin renewal.

In many cases, combining treatments provides the most dramatic and long-lasting improvement. The best option is the one that addresses your specific scar type while keeping your skin safe and healthy.

FAQs

Fungal acne develops from an overgrowth of yeast, not bacteria. It appears as small, itchy bumps, often on the chest, back, or face, and requires antifungal treatment.

Acne prone skin produces excess oil, clogs easily, and often breaks out. Using gentle, non-comedogenic skincare helps reduce flare-ups and keep the skin balanced.

Hormonal acne is triggered by hormone fluctuations, often around the jawline or chin. It usually worsens during puberty, monthly cycles, pregnancy, or stressful periods.

Cystic acne is the most severe type, causing deep, painful lumps under the skin. It often leaves scars and requires professional medical treatment.

Bacterial acne happens when bacteria grow in clogged pores, causing inflammation and pus-filled spots. Treatments often include antibiotics or benzoyl peroxide.

Effective options for acne scars include laser therapy, chemical peels, microneedling with PRP, and topical retinoids. The best treatment depends on your skin and scar type.

Acne is usually worst during the teenage years (12-18), when hormone levels peak. However, many adults also experience acne well into their 30s or later.

A yeast imbalance on the skin causes fungal acne. Heat, sweating, tight clothing, and prolonged antibiotic use can all make it worse.

Acne is a broader skin condition that can include blackheads, whiteheads, pimples, or cysts. Pimples are just one type of acne, usually red and pus-filled.
