The best way to get rid of acne is a combination of topical treatments that target multiple causes at once, not a single miracle product. Acne forms through a chain reaction: your oil glands overproduce sebum, dead skin cells clog the pore, bacteria multiply inside, and inflammation follows. Effective treatment interrupts more than one of those steps simultaneously.
Start With the Right Over-the-Counter Products
Two ingredients form the backbone of any acne routine: benzoyl peroxide and a retinoid. Benzoyl peroxide kills acne-causing bacteria on contact and doesn’t lead to bacterial resistance the way antibiotics can, which is why dermatology guidelines recommend pairing it with almost every other acne treatment. It comes in concentrations from 2.5% to 10%, but lower strengths work nearly as well with less irritation. You can use it as a wash (leaving it on for one to two minutes before rinsing) or as a leave-on gel.
Retinoids are the other cornerstone. They speed up skin cell turnover so dead cells don’t accumulate and plug your pores. Adapalene 0.1% is available without a prescription in most countries and is a good starting point. Prescription-strength options like tretinoin and tazarotene are more potent. In clinical comparisons, tazarotene reduced papules and open comedones faster than tretinoin, and achieved results comparable to adapalene even when applied only every other day instead of daily. All retinoids cause some dryness and peeling in the first few weeks, which typically settles as your skin adjusts.
Salicylic acid (usually 0.5% to 2%) is a useful addition if your skin doesn’t tolerate benzoyl peroxide well. It dissolves the oily buildup inside pores and has mild anti-inflammatory effects, but on its own it’s less effective than benzoyl peroxide for moderate acne.
Why Combining Treatments Works Better
The American Academy of Dermatology specifically recommends using topical therapies that combine multiple mechanisms of action. In practice, this means pairing a retinoid (which unclogs pores) with benzoyl peroxide (which kills bacteria) and sometimes adding a topical antibiotic for the first few months. Using these together attacks acne from different angles. One study on moderate acne found that combining a light-based therapy with a salicylic acid treatment produced a 66% reduction in skin lesions at four weeks, compared to roughly 59% with the light therapy alone and 52% with salicylic acid alone. The principle holds across treatments: layering beats relying on a single product.
Give any new routine at least 12 weeks before deciding it isn’t working. Acne treatments prevent new breakouts from forming underground, and those developing lesions still need time to surface and clear.
When to Consider Prescription Options
If over-the-counter products haven’t made a meaningful difference after three months of consistent use, prescription treatments are the next step. For moderate acne, a doctor may add a short course of oral antibiotics to your topical regimen. Guidelines recommend limiting oral antibiotics to 12 weeks when possible, extending to a maximum of six months only in unusual cases, to prevent bacterial resistance. Antibiotics should always be used alongside benzoyl peroxide, never alone.
For women whose acne flares around their menstrual cycle or clusters along the jawline and chin, hormonal treatments can be highly effective. Spironolactone, a medication that blocks the effect of androgens on oil glands, produced an average improvement of about 73% on facial acne in a retrospective study of 110 women. Most started at 100 mg per day, with higher doses available for those who needed them. Combined oral contraceptives are another hormonal option recommended by the AAD.
Isotretinoin for Severe or Resistant Acne
Isotretinoin (once known by the brand name Accutane) is the most powerful acne treatment available. It shrinks oil glands dramatically, normalizes skin cell shedding, and reduces inflammation all at once. A typical course lasts four to six months, and roughly 70% of patients stay in long-term remission after completing it. The target is a cumulative dose based on body weight, so someone weighing around 130 pounds would take a total of approximately 7,200 to 9,000 mg spread across the entire treatment period.
Isotretinoin comes with significant side effects, including extreme dryness of the skin and lips, potential mood changes, and serious risks during pregnancy. It requires regular blood monitoring and, for people who can become pregnant, strict pregnancy prevention measures. Despite the side effects, it remains the single most effective option for severe, scarring, or treatment-resistant acne, and many people describe it as life-changing.
How Diet Affects Breakouts
Diet doesn’t cause acne on its own, but it can make existing acne worse. The strongest evidence points to high-glycemic foods: white bread, sugary drinks, white rice, and processed snacks that spike your blood sugar quickly. A systematic review found that 77% of observational studies linked high-glycemic diets to worse acne. In one controlled trial, people who switched to a low-glycemic diet for 12 weeks saw their total lesion count drop by 22 on average, compared to a drop of about 11 in the control group. Another 10-week trial found a low-glycemic diet reduced acne severity by nearly 71% from baseline.
The connection between dairy and acne is less clear-cut. About 70% of studies found some link between dairy consumption and breakouts, but the effect seems concentrated in populations eating a Western-style diet. No controlled intervention trials have tested removing dairy to confirm it helps. If you suspect dairy triggers your breakouts, cutting it out for a few months is a reasonable experiment, but it’s not a guaranteed fix.
Protecting Your Skin Barrier During Treatment
Acne treatments work partly by increasing skin cell turnover and reducing oil, which means dryness, flaking, and irritation are common, especially in the first month. A damaged skin barrier can actually trigger more breakouts and make your face red and sensitive, undermining your whole routine. Using a simple, non-comedogenic moisturizer is not optional when you’re on active treatment.
Look for moisturizers containing ingredients like glycerin, hyaluronic acid (often listed as sodium hyaluronate), niacinamide, or dimethicone. These hydrate without clogging pores. Avoid heavy plant oils and thick occlusive creams unless they’re specifically labeled non-comedogenic. Gentle, fragrance-free cleansers are also worth the switch: harsh scrubs and foaming washes strip the skin and worsen irritation from retinoids and benzoyl peroxide.
Sunscreen matters too, since retinoids and several acne medications increase sun sensitivity. A lightweight, non-comedogenic sunscreen with at least SPF 30 keeps treatment-related dark spots from getting worse and protects healing skin.
Building a Practical Routine
For mild to moderate acne, a straightforward routine looks like this: wash with a gentle cleanser morning and night, apply benzoyl peroxide in the morning (a thin layer over acne-prone areas, not just individual spots), moisturize, and apply sunscreen. At night, use your retinoid after cleansing, wait a few minutes for it to absorb, then moisturize. If your skin is too irritated, start the retinoid every other night and build up to nightly use over three to four weeks.
Resist the urge to add multiple new products at once. If you introduce one product at a time, spaced about two weeks apart, you can identify what’s helping and what’s causing irritation. Picking at breakouts, over-washing, and switching products every few days are among the most common reasons people feel like “nothing works.” Consistency over weeks, not days, is what produces visible results.
