Dermatologists recommend treating acne with a combination of topical products that target different causes of breakouts, rather than relying on a single ingredient. For mild acne, that usually means pairing a retinoid with benzoyl peroxide. For moderate to severe cases, oral medications enter the picture. The American Academy of Dermatology specifically emphasizes using multiple mechanisms of action together, limiting antibiotic courses, and tailoring treatment to acne type.
Topical Treatments: The Foundation
Three topical ingredients form the backbone of nearly every dermatologist-recommended acne plan: retinoids, benzoyl peroxide, and salicylic acid. In a survey of dermatologists, 96.8% endorsed retinoids as effective for acne, 95.2% endorsed benzoyl peroxide, and 93.6% endorsed salicylic acid. These aren’t interchangeable, though. Each one works differently, and combining them is the whole point.
Retinoids are vitamin A derivatives (adapalene is the most common over-the-counter version, available as a 0.1% gel). They speed up skin cell turnover so dead cells don’t clog pores, and they also reduce inflammation by calming your skin’s immune response. Retinoids treat both blackheads and inflamed pimples, which is why dermatologists consider them a first-line treatment for almost all acne types. They can cause dryness and flaking when you first start, and it often takes six to twelve weeks before you see real improvement.
Benzoyl peroxide kills acne-causing bacteria and is the go-to for red, pus-filled pimples. It’s also the key ingredient dermatologists pair with antibiotics to prevent bacterial resistance. It comes in concentrations from 2.5% to 10%, but higher isn’t always better. It can bleach fabric, and it’s more drying than other options. If you have eczema, psoriasis, or seborrheic dermatitis, it may be too irritating.
Salicylic acid works best for blackheads and whiteheads. It dissolves the debris inside pores rather than killing bacteria. It’s milder than benzoyl peroxide, making it a better fit for sensitive skin.
Other Recommended Topicals
Azelaic acid (endorsed by 87.1% of dermatologists in that same survey) reduces inflammation and helps fade post-acne dark spots, making it especially useful for darker skin tones. Clascoterone is a newer topical cream, FDA-approved for patients 12 and older, that blocks androgen receptors in the skin. Androgens are hormones that ramp up oil production, so clascoterone targets a hormonal root of acne without being an oral medication.
When Topicals Aren’t Enough: Oral Medications
If your acne is moderate to severe, or if topical treatments alone haven’t cleared it after a few months, dermatologists move to oral options. The AAD guidelines recommend several categories, and the choice depends on the type and pattern of your breakouts.
Oral antibiotics reduce the bacteria and inflammation driving acne. Dermatologists typically prescribe them for the shortest effective period, usually three to four months, though some people need longer. The emphasis on short courses is deliberate: prolonged antibiotic use breeds resistant bacteria, which makes infections harder to treat down the road. That’s also why antibiotics are always paired with benzoyl peroxide and other topicals rather than used alone.
Hormonal therapies are an option for women whose acne flares around their period or clusters along the jawline and chin. Combined oral contraceptives reduce the androgens that trigger oil production. Spironolactone, originally developed for blood pressure, has been used by dermatologists for years to treat acne and excess hair growth in women. It requires a gradual dose increase, with check-ins every four to six weeks at the start.
Isotretinoin for Severe or Resistant Acne
Isotretinoin is reserved for severe acne that causes deep, painful cysts and nodules (often the size of a pencil eraser or larger) or for acne that hasn’t responded to other treatments. It’s the most powerful option available and can produce long-lasting clearance, sometimes permanently, after a single course. The treatment typically lasts several months and requires close monitoring with regular blood tests and, for people who can become pregnant, strict pregnancy prevention measures because the drug causes serious birth defects.
Most people experience significant dryness of the skin, lips, and eyes during treatment. Despite the side effects, isotretinoin remains the most effective tool for acne that doesn’t budge with anything else.
What to Expect in the First Few Months
One of the most frustrating parts of starting acne treatment is that your skin can look worse before it gets better. This is sometimes called “purging,” and it happens most often with retinoids. The medication pushes clogged material to the surface faster, so you get a temporary wave of breakouts in the areas you’re treating.
A purge is different from a bad reaction to a product. Purging shows up only where you applied the treatment and improves over time. A product reaction can spread to untreated areas and gets worse the longer you use it. Most people see improvement after about six weeks of consistent use, though it can take two to three months for acne treatments to fully clear spots. This timeline is why dermatologists stress patience and consistency rather than switching products every few weeks.
Diet and Lifestyle Adjustments
Diet doesn’t cause acne on its own, but the evidence linking blood sugar spikes to breakouts is substantial. When your blood sugar rises quickly, your body produces more insulin, which triggers inflammation and increases oil production in the skin. Both of those fuel acne.
A low-glycemic diet, one that avoids foods causing rapid blood sugar spikes, has shown measurable results. In a U.S. study of over 2,200 patients placed on a low-glycemic diet, 87% reported less acne and 91% said they needed less acne medication. Smaller studies in Australia and Korea found that young adults who switched to low-glycemic eating for 10 to 12 weeks had significantly less acne than those eating their usual diet.
High-glycemic foods to limit include white bread, white rice, corn flakes, potato chips, fries, pastries, and sugary drinks. Lower-glycemic alternatives include most fresh vegetables, beans, steel-cut oats, and many fresh fruits. You don’t need to overhaul your entire diet. Swapping a few high-glycemic staples can make a noticeable difference over a couple of months.
Building a Daily Routine That Works
Dermatologists generally recommend a simple routine over a complicated one. A gentle, non-comedogenic (non-pore-clogging) cleanser, one active treatment product, and a lightweight moisturizer form the core. Sunscreen during the day is essential if you’re using retinoids or benzoyl peroxide, since both increase sun sensitivity.
Layering too many active ingredients at once, like using salicylic acid, benzoyl peroxide, and a retinoid all in the same routine, is a common mistake that leads to irritation without faster results. A better approach is using a retinoid at night and benzoyl peroxide in the morning, or alternating nights. If your skin is sensitive, start with the active ingredient every other night and build up frequency as your skin adjusts. The goal is consistent, long-term use rather than aggressive short bursts.
