Acne: What Works, What Doesn’t, and When to See a Dermatologist
Acne is the most common skin condition in the world, affecting most teenagers and a surprising number of adults. It is not caused by dirt or poor hygiene, and it is not simply a cosmetic issue: severe acne can scar the skin and weigh heavily on confidence and mental health. Effective treatments exist at every level.
How acne develops
Four processes combine in the hair follicle and its oil gland:
- Increased oil (sebum) production, driven by androgen hormones
- Clogging of the follicle with dead skin cells
- Growth of Cutibacterium acnes, a skin bacterium that thrives in the oily environment
- Inflammation, causing red, tender lesions
The result is blackheads and whiteheads (comedones), red papules, pus-filled pustules and, in severe forms, deep painful nodules and cysts.
Who gets it and why it lingers
Puberty raises androgens and triggers acne in the teenage years, but it can persist or begin in adulthood, particularly in women, linked to hormonal fluctuations, polycystic ovary syndrome, stress, some medications and certain cosmetics. Genetics play a major role: if your parents had severe acne, you are more likely to.
Myths worth dropping
- Scrubbing harder does not help. Over-washing and harsh scrubs irritate skin and worsen inflammation. Wash gently twice a day.
- Chocolate and greasy food are not major causes, although high-glycaemic diets and, in some people, skimmed milk may contribute.
- Sun does not cure acne, and some treatments make you sun-sensitive.
- Popping spots increases scarring and infection.
Over-the-counter options
- Benzoyl peroxide (2.5 to 5 per cent) kills bacteria and reduces inflammation. It can bleach fabrics and cause dryness, so start slowly.
- Salicylic acid helps unclog pores.
- Adapalene gel, now available without prescription in many countries, is a retinoid that prevents comedones and is a cornerstone of treatment.
- Azelaic acid reduces inflammation and post-acne marks.

Give any new treatment six to eight weeks before judging it. Skin often looks a little worse before it improves.
Prescription treatments
Topical combinations. Retinoids combined with benzoyl peroxide or a topical antibiotic such as clindamycin are often first-line for mild to moderate acne.
Oral antibiotics. Doxycycline or lymecycline can calm inflammatory acne but should be used for a limited period, typically three months, and always combined with a topical product such as benzoyl peroxide to limit antibiotic resistance.
Hormonal therapy. In women, combined oral contraceptives and the anti-androgen spironolactone can reduce oily skin and hormonal breakouts. They are not suitable for everyone, so seek advice.
Isotretinoin. For severe, scarring or treatment-resistant acne, isotretinoin is the most effective medicine and can lead to long-lasting clearance. It requires specialist supervision, blood tests and strict pregnancy prevention because it causes serious birth defects. It commonly dries the lips and skin, and mood changes should be reported promptly.
Skin care routine
- Cleanse gently with a mild, non-soap cleanser
- Use an oil-free, non-comedogenic moisturiser, since dry irritated skin worsens acne
- Apply sunscreen daily, choosing a light, non-comedogenic formula
- Remove make-up at night
- Avoid picking
- Wash hair regularly if it falls on the face
Dealing with scars and marks
Early effective treatment is the best way to prevent scars. Post-inflammatory dark marks fade over months and respond to azelaic acid, vitamin C, retinoids and strict sun protection. Established scars may improve with microneedling, chemical peels, laser treatments or fillers, best discussed with a dermatologist.
Emotional wellbeing
Acne can affect mood, relationships and self-image. If it is making you anxious or low, tell a clinician. Treatment of the skin and support for mental health can go hand in hand.
When to see a doctor
Seek advice if over-the-counter treatments have not helped after two to three months, if you have deep nodules or scarring, if acne appears suddenly in adulthood along with irregular periods or excess hair, or if it is affecting your wellbeing.
