A dermatologist typically prescribes a combination of topical and sometimes oral medications tailored to your acne severity. For mild acne, that usually means a prescription retinoid paired with benzoyl peroxide or a topical antibiotic. Moderate acne often calls for oral antibiotics added to that topical regimen. Severe or scarring acne may require isotretinoin, and hormonal acne in women is frequently treated with spironolactone.
Topical Retinoids: The Foundation
Nearly every acne prescription starts with a topical retinoid. These medications speed up skin cell turnover, preventing dead cells from clogging pores and helping clear existing blockages. They also reduce inflammation beneath the skin’s surface, which makes them effective against both blackheads and red, inflamed breakouts.
The most commonly prescribed options include tretinoin (available in creams and gels ranging from 0.01% to 0.1%), adapalene (0.1% and a stronger 0.3% gel), tazarotene (0.05% and 0.1%), and trifarotene, a newer retinoid approved for use on both the face and trunk. Adapalene 0.1% is also available over the counter, so your dermatologist may recommend the prescription-strength 0.3% version if you’ve already tried the lower dose without success. Tazarotene tends to be the most potent but also the most irritating, while adapalene is generally the best tolerated.
Expect some dryness, peeling, and redness in the first few weeks. Many dermatologists recommend starting three nights per week and gradually increasing frequency. If your skin is especially sensitive, the “sandwich method” can help: apply moisturizer first, then the retinoid, then another layer of moisturizer. This buffering technique reduces the retinoid’s penetration by roughly threefold, which lets your skin adapt more comfortably. A single layer of moisturizer underneath (the “open sandwich”) slightly slows absorption without meaningfully reducing effectiveness, making it a good middle ground. Another option for very reactive skin is short-contact application, where you leave the retinoid on for about 30 minutes, then rinse it off and moisturize.
Topical Antibiotics and Benzoyl Peroxide
Topical clindamycin is the most frequently prescribed antibiotic for acne, but dermatologists almost never prescribe it alone. Using an antibiotic by itself promotes bacterial resistance, so it’s paired with benzoyl peroxide, which kills acne-causing bacteria through a mechanism that doesn’t lead to resistance. This pairing is so standard that several fixed-dose combination products exist, such as gels containing clindamycin 1.2% with benzoyl peroxide 3%.
In recent years, the options have expanded significantly. The first FDA-approved triple combination gel, approved in October 2023, packages clindamycin, benzoyl peroxide, and adapalene into a single product for once-daily use. Other two-in-one combinations pair a retinoid directly with benzoyl peroxide (adapalene 0.1% with benzoyl peroxide 2.5% is the most widely prescribed). These all-in-one products simplify routines, which matters because simpler regimens tend to produce better results simply because people stick with them.
Clascoterone: A Newer Topical Option
Clascoterone is the first topical androgen blocker approved for acne, and it works differently from every other topical on this list. Instead of killing bacteria or speeding up cell turnover, it blocks hormone receptors in the skin that drive oil production. This is the same hormonal pathway that spironolactone targets orally, but because clascoterone works locally on the skin, it can be used by both men and women.
The updated 2024 guidelines from the American Academy of Dermatology conditionally recommend clascoterone for acne treatment, noting it isn’t restricted to any particular severity level. Patients who’ve tried it report fewer of the dryness and irritation issues common with retinoids and benzoyl peroxide. The main barrier right now is cost, which remains high compared to established treatments.
Oral Antibiotics for Moderate Acne
When topicals alone aren’t enough, dermatologists add an oral antibiotic. The tetracycline family dominates here: doxycycline, minocycline, and the newer sarecycline are all taken once daily. Doxycycline is prescribed most often, typically at either a standard dose (around 100 mg daily) or a lower anti-inflammatory dose (40 mg daily) that reduces inflammation without reaching antibiotic-level concentrations in the body.
Minocycline and sarecycline use weight-based dosing. In clinical trials, sarecycline at 1.5 mg per kilogram of body weight reduced inflammatory lesions by about 53% after 12 weeks, compared to 38% with placebo. Sarecycline has a narrower spectrum of activity, meaning it targets fewer types of bacteria and may cause less disruption to your gut microbiome.
Oral antibiotics are meant as a bridge, not a long-term solution. Most dermatologists prescribe them for roughly three to four months while your topical regimen takes full effect, then taper off. Long-term antibiotic therapy is not recommended due to resistance concerns.
Spironolactone for Hormonal Acne
For women whose acne is driven by hormonal fluctuations, particularly breakouts along the jawline, chin, and lower face, spironolactone is a widely used off-label treatment. It blocks androgen receptors and reduces the hormonal signals that ramp up oil production.
Most dermatologists start at 100 mg daily. In a retrospective study of 110 women, 85 out of 101 patients who started at this dose showed improvement, and 40 cleared completely. Those who didn’t fully respond were moved to 150 mg or 200 mg daily, with additional patients clearing at each step. Because spironolactone affects potassium levels, your dermatologist will check bloodwork periodically. It’s prescribed only for women because its anti-androgen effects can cause problems in men.
Isotretinoin for Severe Acne
Isotretinoin is the most powerful acne treatment available and the only one that can produce long-term remission after a single course. It’s reserved for severe, scarring, or treatment-resistant acne. The medication shrinks oil glands dramatically, reduces bacterial colonization, slows skin cell buildup in pores, and lowers inflammation all at once.
Treatment typically starts at 20 to 30 mg daily for the first couple of weeks, then increases to a target of 0.5 to 1 mg per kilogram of body weight per day. The goal is to reach a cumulative dose of 120 to 150 mg per kilogram over the full course. For someone weighing about 130 pounds (60 kg), that means a total of 7,200 to 9,000 mg spread across roughly four to six months of treatment.
Isotretinoin requires monthly monitoring through a program called iPLEDGE, which includes regular blood tests and, for patients who can become pregnant, monthly pregnancy tests. The drug causes severe birth defects, so reliable contraception is mandatory. Side effects during treatment are common: dry lips, dry skin, dry eyes, joint aches, and sometimes mood changes. Most of these resolve after stopping the medication. The payoff is significant. The majority of patients experience lasting clearance, though a smaller percentage need a second course.
What the First Weeks Look Like
No matter which medications your dermatologist prescribes, visible improvement takes time. Most topical treatments need six to eight weeks before you notice meaningful changes, and full results often take three to four months. During the first four to six weeks on a retinoid, you may experience “purging,” a temporary flare where existing clogged pores come to the surface faster than they normally would. This looks like a worsening of your acne, but it’s actually a sign the medication is accelerating turnover in your skin. If the flare continues past six weeks, that’s worth raising with your dermatologist, since it may signal the need for an adjustment.
Oral antibiotics tend to show faster initial improvement because they reduce inflammation systemically, which is one reason dermatologists use them as a bridge while slower-acting topicals build up their effect. The key to success with any prescription acne regimen is consistency through that awkward early phase when your skin looks worse before it looks better.
