Acne: what works, what doesn't
Acne is a disease of the oil gland and the follicle, driven by hormones, sebum, bacteria and inflammation. It is treated in layers: skincare for mild disease, prescription topicals and tablets for moderate and severe disease, and procedures for the flares, the cysts and the marks left behind. The order matters more than the brand, and the goal that matters most is preventing scars.

What works for acne?
The evidence-based foundation is topical retinoids and benzoyl peroxide for mild to moderate acne, with azelaic acid and niacinamide as adjuncts; oral antibiotics for a limited course in moderate inflammatory acne; hormonal treatment for adult female acne; and oral isotretinoin for severe, nodular or scarring acne, the one medicine with lasting remission. Procedures earn their place around the medicine: steroid injection for a painful cyst, chemical peels and light-based treatments for stubborn comedonal and inflammatory acne, and the 1726 nm lasers as a newer, device-based route to the sebaceous gland. Facials, 'detox' routines and most supplements do not change the course of acne.

By the numbers
- systematic review
Across 31 trials, isotretinoin improved acne; evidence quality was low and no clear difference from oral antibiotics plus topical treatment was shown on the primary outcome, while adverse effects — mainly mucocutaneous — were more frequent.
From the Isotretinoin for acne review — Oral isotretinoin for acne., Cochrane Database Syst Rev, 2018. PMID 30484286.
- RCT
In a 12-week double-blind, vehicle-controlled split-face trial, 5% niacinamide improved fine lines, hyperpigmented spots, red blotchiness and elasticity.
From the Niacinamide review — Niacinamide: A B vitamin that improves aging facial skin appearance, Dermatol Surg, 2005. PMID 16029679.
- RCT
Both 0.1% and 0.025% tretinoin improved photoaged skin over vehicle, with the lower strength causing less irritation.
From the Retinoids: retinol, retinal and prescription retinoids review — Two concentrations of topical tretinoin (retinoic acid) cause similar improvement of photoaging but different degrees of irritation, Arch Dermatol, 1995. PMID 7544967.

- NiacinamideIt will not change a face, but it makes everything else in the routine easier to tolerate, which is worth more than most hero ingredients deliver.Established
- Retinoids: retinol, retinal and prescription retinoidsThe mistake is not choosing the wrong retinoid; it is quitting in week three.Established
- Azelaic acidFor the Singapore face that is red, bumpy and marked all at once, it is often the first thing we reach for before any device.Established
- Chemical peelsThe result is written in the depth and the priming, not in the brand on the bottle.Established
- Isotretinoin for acneThe side effects are real and mostly manageable; the pregnancy rule is absolute.Established
- Oral antibiotics for acneThree months with a retinoid alongside is the job; if acne returns each time it stops, the next conversation is isotretinoin or, for women, spironolactone.Established
- Double cleansing and oil cleansingThe question is not whether to double cleanse but whether your first cleanser rinses off; the ones that do not are the ones that clog.Established
- Fungal acne (Malassezia folliculitis)Cheap to treat, easy to miss, and likely to come back in the heat.Established
- BBL and IPL photofacialThe light is broad and so is the risk: fair skin gets a photofacial, tanned skin gets a burn, and the marketing about genes is a footnote.Established
- Spironolactone for adult female acneSlow to start, reliable to maintain.Established
- Pimple patchesThat alone prevents more scars than most serums; the rest of your acne still needs a plan.Established
- Back and body acneThe traps are fungal folliculitis mistaken for acne and scrubbing that makes everything worse.Established
- Acne lasers: AviClear and AccureThe data are young and industry-funded, and 'cure' belongs to the press release, not the papers.Promising
- Red light and LED masksA harmless, pleasant adjunct with small, slow benefits. Skin maintenance is a rhythm, not a rescue — this is rhythm, not rescue.Trend
- HydraFacialA good facial, honestly labelled. Between treatments, maintain your results — this is maintenance.Trend
- Snail mucinA trend with a pleasant texture. It hydrates, which is honest work; the healing folklore belongs to the snail, not the bottle.Trend
- Beef tallow skincareA trend that rediscovered the occlusive moisturiser and gave it a smell. If your skin is dry, petrolatum does the same job with a safety record; if it is acne-prone, keep the beef on the plate.Trend
- Skin fasting and the 'caveman method'Fewer products is often good advice; no water is not advice, it is a dare. The skin does not need a fast, it needs a cleanser it can tolerate and a routine short enough to keep.Caution
