How to get rid of acne: what actually works, by severity (2026)
Acne isn't about being dirty, and scrubbing makes it worse. The evidence-based fixes are specific: benzoyl peroxide and retinoids for most cases, prescription options for stubborn or hormonal acne, and isotretinoin for severe. Here's the plan by severity, straight from the dermatology guideline.

First, what acne actually is
Acne is not a hygiene problem. It's driven by four things working together: pores getting clogged with dead skin cells, excess oil (sebum), the acne bacterium Cutibacterium acnes, and inflammation [1]. That's why 'wash more' fails and scrubbing backfires — irritation and a damaged skin barrier make acne worse, not better.
Understanding those drivers explains the treatments: they each target one or more of them, which is why the effective options are specific ingredients rather than harder washing.
The evidence-based core (most people)
The American Academy of Dermatology guideline centers on a few proven topicals [1]. Benzoyl peroxide kills acne bacteria and, importantly, reduces antibiotic resistance, which is why it's often paired with antibiotics. Topical retinoids (adapalene, tretinoin, tazarotene) unclog pores and normalize skin-cell turnover, treating and preventing both clogged pores and inflammation.
For many people, a combination — a retinoid plus benzoyl peroxide — is the backbone. Salicylic acid and azelaic acid are useful adjuncts. Consistency over 8 to 12 weeks is what delivers results; see our tretinoin-purge guide for getting through the retinoid adjustment.
Adding antibiotics and hormonal treatment
For inflammatory acne (red, pus-filled bumps), the guideline supports topical or oral antibiotics — but always paired with benzoyl peroxide and used for a limited time to curb resistance, not as a standalone long-term fix [1].
For women whose acne is hormonal (jawline and chin, cyclical flares), hormonal therapy is highly effective: combined oral contraceptives and the anti-androgen spironolactone both counter the hormonal drivers. These are prescription options a clinician tailors, frequently alongside topicals.
Severe acne: isotretinoin
For severe, nodular, or scarring acne — or acne that hasn't responded to other treatments — oral isotretinoin is the most effective option and can produce long-lasting remission [1]. It's a serious medication requiring monitoring and, critically, strict pregnancy prevention for anyone who can become pregnant because it causes severe birth defects.
The reason to escalate rather than keep struggling is scarring: significant acne can leave permanent marks, so treating it effectively and early protects your skin long-term. This is a clinician-managed decision.
What to skip
Skip the myths and the harsh stuff. Aggressive scrubbing, abrasive cleansers, and 'drying out' the skin damage the barrier and worsen acne. Toothpaste, lemon juice, and most viral 'natural' hacks aren't treatments. Picking and popping raises the risk of scarring and dark spots. And 'acne supplements' are not a substitute for the proven topicals and prescriptions.
The one dietary caveat with any evidence is that high-glycemic diets (and possibly skim dairy) may aggravate acne for some people — a reasonable thing to tweak, but not a replacement for treatment.
The bottom line
Acne is treatable, but with specific evidence-based tools, not scrubbing: benzoyl peroxide and topical retinoids for most cases, antibiotics (with benzoyl peroxide) or hormonal therapy for inflammatory or hormonal acne, and isotretinoin for severe or scarring acne [1]. Give a regimen 8 to 12 weeks, be gentle with your skin, and see a clinician for moderate-to-severe or scarring acne early — because preventing scars is far easier than fixing them.

What actually gets rid of acne?
The evidence-based core, per the American Academy of Dermatology guideline, is topical treatments that target the causes of acne: benzoyl peroxide (kills acne bacteria and reduces resistance), topical retinoids (unclog pores and normalize skin turnover), and, for inflammatory acne, topical or oral antibiotics used alongside benzoyl peroxide. For hormonal acne in women, hormonal treatments (combined oral contraceptives or spironolactone) help, and for severe, scarring acne, oral isotretinoin is the most effective option. The right mix depends on your acne's type and severity — and consistency over 8 to 12 weeks matters more than any single product.
Does washing your face more get rid of acne?
No — and over-washing or scrubbing makes it worse. Acne is not caused by dirt; it's driven by clogged pores, oil, acne bacteria, and inflammation. Harsh scrubbing, hot water, and aggressive cleansers irritate and damage the skin barrier, which can worsen breakouts and cause redness. Gentle cleansing twice a day with a mild cleanser is all that's needed on the washing front; the actual treatment comes from the ingredients above, not from scrubbing harder.
How long does acne treatment take to work?
Give it about 8 to 12 weeks before judging. Acne treatments work by preventing new breakouts, so they act gradually rather than clearing existing pimples overnight, and retinoids can even cause a temporary 'purge' early on. This slow timeline is the number-one reason people quit too soon and conclude 'nothing works.' Pick an evidence-based regimen, use it consistently, and reassess at roughly the 3-month mark rather than after a week.
What's the best treatment for hormonal acne?
For women with hormonal acne (often along the jaw and chin, flaring with the menstrual cycle), hormonal therapies are effective and guideline-supported: combined oral contraceptives and the anti-androgen spironolactone both reduce acne by countering the hormonal drivers. These are prescription treatments a clinician manages, often alongside topical retinoids and benzoyl peroxide. If your acne is cyclical and resistant to standard topicals, it's worth asking specifically about the hormonal angle.
When should I see a dermatologist or consider isotretinoin?
See a clinician if your acne is moderate to severe, scarring, leaving dark marks, or not responding to over-the-counter benzoyl peroxide and retinoids after a couple of months. For severe, nodular, or scarring acne, oral isotretinoin is the most effective treatment and can produce lasting remission — it requires monitoring and, for those who can become pregnant, strict pregnancy prevention because it causes severe birth defects. Early treatment of significant acne matters because it prevents permanent scarring.

Starting a retinoid often makes skin break out, flake, and look worse for a few weeks — the 'purge.' It happens because retinoids speed up how fast skin turns over, surfacing clogs that were already forming. Here's how long it lasts, how to tell purging from irritation, and how to get through it.
