“What’s the most effective treatment for acne?” is one of the most common questions our clinicians answer. The honest answer is that there isn’t one universal best treatment — there’s a treatment ladder, and the most effective option depends on the severity of your acne, what you’ve already tried, your skin type, your age, and whether scarring has started to develop.
This guide walks through the full ladder — topical actives, prescription medications, in-clinic procedures, and laser — explains what each does well and where each falls short, and sets out where laser acne treatment sits relative to everything else. For most patients with persistent moderate-to-severe acne, properly delivered Nd:YAG laser therapy with the Fotona SP Dynamis Pro is the most effective single intervention available — but it’s not the right starting point for everyone.
Why “best treatment” depends on what you’ve got
Acne is graded by severity, by lesion type, and by whether scarring is forming. The most efficient treatment for mild comedonal acne (blackheads and whiteheads) is completely different from the most efficient treatment for severe inflammatory cystic acne. Mismatch the treatment to the grade and you’ll either over-treat (unnecessary side effects, expense, downtime) or under-treat (no progress, while scarring continues to accumulate).
The starting point is honest grading:
- Mild acne — predominantly non-inflammatory lesions (blackheads, whiteheads), occasional papules and pustules, limited distribution. Topical therapy is usually sufficient.
- Moderate acne — more numerous papules and pustules, some inflammatory lesions, wider distribution. Combination topical and oral therapy, sometimes with adjunctive in-clinic treatment, is often needed.
- Severe acne — extensive inflammatory papules and pustules, nodules and/or cysts, real risk or evidence of scarring. Aggressive treatment is justified — typically isotretinoin or laser, sometimes both in sequence.
Lesion type matters too. Comedonal acne responds to retinoids and exfoliation. Inflammatory papulopustular acne responds to antimicrobials and anti-inflammatories. Cystic acne needs systemic treatment or laser. We discuss specific cystic acne management in detail in our Fotona laser treatment for cystic acne guide.
Tier 1: Topical actives — the foundation
For most patients with mild to moderate acne, the first rung is well-chosen topical therapy. Done well, topicals can clear mild acne completely and substantially improve moderate cases. Done badly — wrong product, wrong concentration, inconsistent application, no sun protection — they fail and patients lose months they could have spent treating effectively.
Benzoyl peroxide
Benzoyl peroxide is the most useful single topical active in acne. It’s antibacterial, mildly comedolytic, and crucially doesn’t drive antibiotic resistance. Available over the counter at 2.5% to 10% concentrations, with prescription-strength formulations available in combination products.
At our clinic we use the Obagi CLENZIderm M.D.™ System as our flagship prescription-strength topical regimen. It contains a patented solubilised form of 5% benzoyl peroxide that penetrates deep into the follicle to treat acne at its source. Used consistently for 12 weeks, the system reduces sebum production, exfoliates effectively to unblock pores, reduces pore size, controls bacterial proliferation, and clears the residual redness that conventional benzoyl peroxide products leave behind.
Topical retinoids
Retinoids — adapalene, tretinoin, tazarotene — are vitamin A derivatives that normalise the shedding of skin cells inside hair follicles, which is what stops the comedones forming in the first place. They’re essential for any acne characterised by blackheads and whiteheads, and they continue working in mixed inflammatory acne too. Expect 8 to 12 weeks before you see clear benefit, and expect an initial irritation phase that has to be managed with adequate moisturiser and sun protection.
Azelaic acid
Azelaic acid is gentler than benzoyl peroxide or retinoids but genuinely effective in mild to moderate acne, particularly when post-inflammatory pigmentation is a concern. It’s our default choice for patients with sensitive skin or darker Fitzpatrick types where benzoyl peroxide irritation drives post-inflammatory hyperpigmentation.
Topical antibiotics
Clindamycin and erythromycin gels reduce bacterial counts and inflammation. They should never be used alone — antibiotic resistance develops rapidly when topical antibiotics aren’t paired with benzoyl peroxide. Used in combination, they’re a reasonable addition to a regimen targeting inflammatory papulopustular acne.
Tier 2: Oral medications — for moderate to severe disease
When topicals alone aren’t enough, oral therapy adds systemic effect. The main options:
Oral antibiotics
Tetracyclines — usually doxycycline or lymecycline — are the workhorse oral antibiotics in acne. They work both through their antibacterial effect and through their anti-inflammatory properties. Typical courses run three to six months, after which patients transition to maintenance topicals to prevent rebound.
Long-term oral antibiotic use is increasingly avoided because of antimicrobial resistance concerns and because of the gut microbiome impact. If a patient needs more than six months of antibiotic therapy to control their acne, they probably need a different treatment approach — laser or isotretinoin.
Hormonal treatments
For women with hormonally driven acne — flares around the menstrual cycle, predominantly along the jawline and lower face, often persisting from puberty into adulthood — hormonal modulation can be transformative. The combined oral contraceptive pill (particularly preparations containing anti-androgenic progestogens) and spironolactone are the two main options. Both work by reducing the androgenic stimulation of sebaceous glands.
For more on the pattern of adult hormonal acne and how it differs from teenage acne, see our guide on adult acne.
Isotretinoin (Roaccutane)
Isotretinoin remains the most powerful systemic treatment for acne. A typical course runs four to six months at a cumulative dose calculated by body weight. It works by dramatically shrinking sebaceous glands, normalising follicular shedding, reducing bacterial colonisation and reducing inflammation — addressing every mechanism of acne formation simultaneously.
The downside is significant: comprehensive contraception requirements for women of reproductive age (the drug is severely teratogenic), routine blood monitoring of liver function and lipids, the prohibition on cosmetic procedures during and for six months after treatment, and a meaningful side-effect profile including mood effects that need careful monitoring. Patients on isotretinoin are managed by dermatologists throughout the course.
For appropriate patients with severe, scarring, or treatment-resistant acne, isotretinoin can deliver near-complete and lasting clearance. For patients who can’t tolerate it or who want to avoid systemic drugs entirely, laser therapy is the most powerful alternative.
Tier 3: In-clinic procedures
Alongside medication, in-clinic procedures accelerate progress and address residual scarring. The principal options:
Chemical peels for acne
Our dermatologists deliver specialist medical-grade chemical peels combining benzoyl peroxide, salicylic acid, glycolic acid, TCA, retinoic acid, vitamin C and kojic acid. The composition is adjusted to the skin type and the dominant concern — active lesions, blackheads, post-inflammatory pigmentation, or early scarring.
Light peels can be performed every two to four weeks as part of an active acne programme. Medium-depth peels — including TCA peels — address established post-acne hyperpigmentation and early atrophic scarring. The recovery from a medium peel is several days of peeling and pinkness; strict sun protection is essential afterwards.
Comedone extractions
Mechanical extraction of blackheads and whiteheads, performed properly with a comedone extractor under clean conditions, removes the lesions without driving the inflammation that DIY squeezing causes. We integrate extractions into chemical peel sessions for patients with comedonal-dominant acne.
Acne scar treatment
Once scarring has developed, the treatment ladder shifts. Atrophic scars — ice pick, boxcar, rolling — respond to fractional ablative laser, RF microneedling, subcision and dermal fillers, with the best results coming from combinations. Our dedicated acne scar removal service uses fractional Er:YAG laser and Morpheus8 RF microneedling to remodel scar tissue and improve surrounding texture.
Tier 4: Laser acne treatment — Nd:YAG on the Fotona SP Dynamis Pro
For persistent moderate-to-severe acne — or for patients who want to avoid systemic medication, can’t tolerate isotretinoin, or have failed other treatments — laser is the most effective single in-clinic intervention available.
At Centre for Surgery we use the Fotona SP Dynamis Pro Nd:YAG laser, with the option to combine Er:YAG resurfacing for patients who also have scarring. The Nd:YAG laser addresses every mechanism driving acne formation, simultaneously:
1. Targeted reduction of sebaceous gland activity
The Nd:YAG laser emits at 1,064 nm, a wavelength that penetrates deep enough to reach the sebaceous glands sitting in the mid-dermis. Photothermal effect at depth shrinks the glands and reduces their sebum output — addressing the foundational driver of acne in the same way isotretinoin does, but without systemic exposure.
2. Bactericidal effect
The heat generated targets Cutibacterium acnes (formerly Propionibacterium acnes) in the follicle, reducing bacterial load without the antibiotic-resistance concerns of long-term oral antibiotics. This is a meaningful clinical and public-health advantage.
3. Anti-inflammatory action
The laser energy modulates inflammatory mediators in the skin, reducing the redness and swelling that surround active lesions. Patients often notice flatter, less angry-looking spots within days of their first session.
4. Collagen stimulation for scar prevention and remodelling
Photothermal stimulation of dermal fibroblasts increases collagen production. For patients early enough to prevent scarring, this is protective. For patients with established mild scarring, the same mechanism softens and remodels scar tissue over a course of treatments.
The treatment protocol
A standard course at our clinic runs:
- Phase 1 (month 1) — two sessions per week to accelerate response
- Phase 2 (months 2–3) — one session per week to consolidate
- Phase 3 (maintenance) — single sessions at increasing intervals to sustain remission
Each session includes six passes with the Nd:YAG handpiece, with mild cold-air cooling for comfort. There’s no downtime — patients return to normal activity immediately. Most patients see meaningful improvement within four to six sessions, with continued progress over the full course.

How to decide where to start on the ladder
The treatment ladder isn’t a fixed sequence — many patients enter it at different points based on their history and severity. A practical starting framework:
- First-time mild acne — start with topical therapy. Benzoyl peroxide or Obagi CLENZIderm M.D.™ as the active ingredient; add a retinoid if comedones predominate. Reassess at 12 weeks.
- Moderate acne, or topical-resistant — add oral therapy (tetracycline antibiotics or hormonal modulation), and consider adjunctive in-clinic treatments. Reassess at 12 weeks.
- Severe acne, or scarring developing — escalate immediately. Laser therapy or isotretinoin, sometimes in sequence (laser first if isotretinoin contraindications exist, or vice versa).
- Treatment-resistant or recurrent — laser becomes a particularly strong option. The mechanism of action differs from oral therapy, so patients who haven’t responded to medication often respond well to laser.
- Post-acne scarring or pigmentation — different treatment ladder entirely. See acne scar removal and hyperpigmentation treatment.
The most common acne treatment mistakes
Across the patients who come to us after failed treatment elsewhere, the same patterns emerge:
- Switching products too quickly — most topicals need 8 to 12 weeks of consistent use before they show meaningful benefit. Switching at six weeks because results aren’t visible yet means starting over each time.
- Skipping sun protection — both medication and laser treatment increase photosensitivity. Without SPF 50 daily, post-inflammatory hyperpigmentation outpaces the acne improvement.
- Aggressive scrubbing or DIY exfoliation — irritates the skin barrier and drives inflammation, making the acne worse.
- Picking and squeezing — the single most preventable cause of acne scarring. Don’t.
- Long-term oral antibiotic use without an exit plan — drives resistance and doesn’t address the underlying cause.
- Avoiding professional input until scarring has set in — by the time scarring has developed, the treatment is harder, longer and more expensive than acne treatment alone would have been.
What we don’t recommend
- Long courses of oral antibiotics as monotherapy — drives resistance, doesn’t fix the underlying mechanism. Combine with topical benzoyl peroxide and exit within six months.
- Microdermabrasion for active acne — superficial abrasion irritates lesions, drives inflammation, and doesn’t reach the sebaceous gland depth where the problem sits. Not part of our offering.
- Heavy occlusive products marketed for acne-prone skin — many “acne-friendly” cosmetic products contain occlusive ingredients that worsen the underlying problem. We provide product guidance in our consultations.
- “Detox” diets and supplements — there’s no evidence of benefit, and the time spent on these is time not spent on treatments that work.
- Single laser sessions as a quick fix — laser acne treatment works as a course, not a one-off. Honest expectations from session one.
Frequently asked questions
How long until I see results?
Topicals: 8 to 12 weeks of consistent use. Oral medications: 6 to 12 weeks. Laser: visible improvement within the first month, with continued progress over the full course. Isotretinoin: initial flare often occurs in the first month with steady clearance from month two onwards.
Will my acne come back after treatment?
Acne is a chronic condition. Treatment achieves remission, not cure. Maintenance — typically a simplified topical regimen plus periodic laser maintenance sessions if relevant — is essential to prevent recurrence. The exception is isotretinoin, which can produce long-lasting clearance in many patients but isn’t appropriate for everyone.
Is laser safe for darker skin types?
Yes — Nd:YAG is one of the safest laser wavelengths for Fitzpatrick types IV to VI because melanin absorbs less of its energy than at shorter wavelengths. We adjust protocols, conduct patch testing where appropriate, and use conservative initial settings. For details on safety across skin types, see our guide on laser safety across Fitzpatrick types.
Can I combine treatments?
Yes, and combinations often outperform any single treatment. Common combinations include laser + topical regimen, laser + hormonal modulation, and chemical peels + topicals. We design combined protocols at consultation.
What does laser acne treatment cost?
Individual session pricing varies by area treated; course packages discount the per-session rate. A consultation gives an exact quote based on the recommended protocol. We offer finance from 0% APR through Chrysalis Finance.
Are over-the-counter products worth using?
For mild acne, well-chosen over-the-counter benzoyl peroxide and a salicylic acid cleanser are a reasonable starting point. For anything more than mild, prescription-strength products (like the Obagi CLENZIderm M.D.™ System) outperform OTC options markedly.
Will diet changes help?
The evidence base is modest. High-glycaemic-index foods and dairy may worsen acne in some patients; the link is real but small. Diet changes are worth trying as an adjunct, but they’re not a substitute for proper treatment.
