Acne Treatment:
Diet, Over-the-Counter Care & Prescription Options
There’s no single “best” acne treatment — the right plan depends on the type of acne you have, its severity, your skin, and how you respond over time. This page walks through the three layers of acne care, roughly in the order most patients move through them: dietary habits, over-the-counter (OTC) products, and prescription therapy. Many patients end up using a combination from more than one category at once, which is normal and often more effective than any single approach alone.
Diet & Acne
Diet is one of the most-asked-about, least-settled areas of acne care, so it’s worth being precise about what the evidence actually supports.
What the research shows
Glycemic index and glycemic load: The most consistent dietary evidence links high-glycemic diets (refined carbohydrates, sugary foods and drinks) to worse acne. Several controlled trials have found a modest but real improvement in inflammatory lesions when patients shift toward a lower-glycemic eating pattern. The proposed mechanism involves insulin and insulin-like growth factor 1 (IGF-1), which can increase androgen activity and sebum production.
Dairy: The evidence here is genuinely mixed. Some large observational studies associate dairy intake — particularly skim milk — with increased acne risk, while others find no significant association. The effect, if real, appears to vary by population and may be more consistently observed in Western dietary patterns. It is not established as strongly or as consistently as the glycemic-load link.
Chocolate, “greasy food,” and other folk associations: Largely unsupported by controlled evidence, though individual sensitivity varies and pure high-sugar chocolate products may act through the same glycemic pathway above.
What this means in practice
Diet is best framed as a potential adjunct to standard medical treatment, not a replacement for it. Dietary changes alone rarely clear moderate-to-severe acne. That said, patients who want to explore the dietary angle can reasonably:
Favor a lower-glycemic eating pattern (whole grains, legumes, vegetables; pairing carbohydrates with protein, fiber, or fat to blunt blood sugar spikes)
Notice, without over-restricting, whether dairy — especially skim milk — seems to correlate with own personal flares
Keep a simple symptom journal if they suspect a personal trigger, rather than eliminating entire food groups
Talk to a dermatologist or registered dietitian before making major or restrictive dietary changes, particularly if there’s any history of disordered eating
We deliberately don’t prescribe a specific diet plan on this page — the evidence DOES NOT support a single protocol, and a board-certified dermatologist or dietitian can help you weigh this alongside your medical treatment.
Over-the-Counter (OTC) Treatments
OTC treatment is a reasonable starting point for mild, mostly comedonal acne. The FDA recognizes a specific set of active ingredients as effective for acne; the two most useful for most patients are below, alongside newer additions to the OTC aisle.
Benzoyl Peroxide
The most effective OTC ingredient at reducing C. acnes, and it works without contributing to antibiotic resistance. Available in leave-on and wash-off formulations from about 2.5% to 10% — notably, lower concentrations (2.5%) are often just as effective as higher ones with less irritation, so more isn’t necessarily better. Can bleach hair, clothing, and towels; apply carefully.
Adapalene 0.1%
A topical retinoid, and the first prescription-strength retinoid to become available OTC (approved for over-the-counter sale in 2016). Adapalene normalizes the shedding of skin cells inside the follicle, addressing hyperkeratinization directly. It’s a slower-acting, preventive-leaning treatment rather than a spot treatment — expect 6–8 weeks before judging results.
A newer option: Adapalene/Benzoyl Peroxide Combination
A fixed-dose combination of adapalene 0.1% and benzoyl peroxide 2.5% — previously prescription-only — has received FDA approval to move over the counter, expanding OTC access to combination therapy that used to require a prescription. Combination products like this are generally more effective than either ingredient alone, since they address hyperkeratinization and bacterial overgrowth at the same time.
Salicylic Acid
A beta-hydroxy acid with mild comedolytic (pore-clearing) and exfoliating effects. Milder than benzoyl peroxide, with correspondingly milder results — often used in cleansers as a maintenance step rather than a primary treatment.
Azelaic Acid (OTC strength)
Available in OTC cosmetic formulations, typically up to around 10%. Has antibacterial, comedolytic, and anti-inflammatory effects, and also helps fade post-inflammatory dark marks. Generally well tolerated, including in pregnancy — though prescription strengths (see below) are studied more extensively for acne specifically.
Other OTC options
Sulfur and resorcinol-based products are older keratolytic options, still available and occasionally useful for patients who don’t tolerate the ingredients above.
Getting the most out of OTC treatment
Introduce one new active ingredient at a time so you can tell what’s working (and what’s causing irritation)
Pair actives with a gentle, non-comedogenic moisturizer — dryness and irritation are the
most common reasons people quit a treatment before it has a chance to work
Use daily sunscreen — benzoyl peroxide and retinoids can both increase sun sensitivity. UV also leads to more post-inflammatory pigment formation.
Give any regimen 6–8 weeks before judging whether it’s working; acne treatments are not fast-acting (antimicrobial effects can show in days, but comedonal/structural improvement takes longer)
Prescription Treatments
When OTC care isn’t enough, or acne is moderate-to-severe from the start, prescription therapy — often combining more than one mechanism — becomes appropriate. The following reflects the general structure of the American Academy of Dermatology’s 2024 acne treatment guideline.
Topical Retinoids
Tretinoin, prescription-strength adapalene, tazarotene, and trifarotene are all FDA-approved topical retinoids. They remain a first-line, strongly-recommended therapy for both comedonal and inflammatory acne, and no one retinoid has been shown to consistently outperform the others. Trifarotene is notable for demonstrated efficacy on truncal (chest/back) acne, an area older retinoids were studied on less.
Topical Antibiotics
Clindamycin is the most commonly prescribed topical antibiotic for acne. To limit antibiotic resistance, it’s almost always paired with benzoyl peroxide, either as two separate products or as a fixed-dose combination.
Clascoterone
A topical androgen receptor inhibitor (brand name Winlevi), FDA-approved since 2020 for patients 12 and older. It works directly at the sebaceous gland, blocking the effect of androgens locally rather than systemically, which makes it an option for patients — including some men — who might otherwise only have systemic hormonal therapy available to target the hormonal component of their acne.
Azelaic Acid (prescription strength)
Prescription formulations (15–20%) are FDA-approved specifically for acne and have demonstrated results comparable to topical retinoids in clinical studies, with a favorable tolerability profile — a reasonable option during pregnancy or for patients who don’t tolerate retinoids or benzoyl peroxide well.
Oral Antibiotics
Reserved for moderate-to-severe inflammatory acne. Doxycycline is the preferred first-line oral antibiotic. Minocycline and sarecycline (a newer, narrower-spectrum tetracycline developed specifically for acne) are also used. Oral antibiotics are always intended as a short course paired with topical therapy, not a long-term solution, to limit resistance and side effects.
Hormonal Therapy
For patients whose acne has a clear hormonal pattern (jawline concentration, cyclical flares, adult-onset), two options are commonly used:
Combined oral contraceptives — several are FDA-approved specifically for acne
Spironolactone — an androgen receptor blocker, taken orally, increasingly used for adult female hormonal acne; healthy patients generally don’t need routine potassium monitoring, though it may be considered for those with risk factors for elevated potassium or in women older than 45 y.o. age
Both are options for patients who can become pregnant and are not appropriate during pregnancy; your dermatologist will discuss contraception and safety before prescribing either.
CHEMICAL PEELS
Chemical peels are one of dermatology’s most versatile and proven tools — capable of addressing everything from mild comedonal acne, to inflamed lesions, and deep scarring. Chemical peels come in various formulations & strengths, and medical grade peels are selected specifically by a Dermatologist depending on skin type and acne presentation. Medical grade peels can be significantly different than what spas and non-Dermatologists may offer. These can reduce active breakouts, decongests pores, and calms inflammation. Downtime is minimal, with mild peeling or flaking possible for 2-4 days. These can be performed in our Complete Acne Institute every 3–4 weeks; a course of 3–6 treatments is recommended.
Intralesional Corticosteroid Injections
A quick in-office injection directly into a large, painful papule or nodule, used to rapidly reduce inflammation in a single problem lesion — useful as an add-on rather than a primary regimen.
Isotretinoin — [Accutane/Rakutane]
Reserved for severe acne, acne causing significant scarring or psychological distress, or acne that hasn’t responded to standard oral and topical therapy — and it’s the strongest recommendation in the AAD’s guideline for that group. Because isotretinoin causes serious birth defects if taken during pregnancy, every patient — regardless of sex — is enrolled in the FDA’s iPLEDGE risk mitigation program, which mandates pregnancy testing and contraception counseling for patients who can become pregnant, along with regular monitoring. iPLEDGE’s specific requirements have been undergoing federally-mandated simplification through 2026 to reduce burden on patients and prescribers while keeping its core safety goals intact, so ask your dermatologist for the program’s current requirements at the time of treatment.
Building Your Treatment Plan
Most effective acne regimens combine therapies that work through different mechanisms — for example, a topical retinoid for hyperkeratinization alongside benzoyl peroxide for bacteria, or a topical regimen alongside hormonal therapy for a patient with a clear hormonal pattern. Our dermatologists build that combination around your specific presentation, and adjust it as your skin responds. We always stress to patients that any treatment plan can take 6-8 weeks to start working, and consistency with any regimen is critical.
When to See a Dermatologist?
Over-the-counter (OTC) care is reasonable for mild, comedonal acne. It’s worth booking a consultation if you notice any of the following:
Nodules or cysts, or acne that’s painful rather than just cosmetically bothersome
Acne that hasn’t improved after 2–3 months of consistent OTC treatment
Any scarring, or dark/red marks that persist after a lesion clears
Acne that’s affecting your confidence or daily life
Sudden, severe onset, especially with fever or joint pain
