A dermatologist treats acne by matching the type and severity of your breakouts to a specific plan, starting with prescription-strength topicals for mild cases and escalating to oral medications, hormone therapy, or in-office procedures when needed. Most people who see a dermatologist for acne have already tried drugstore products without success, and the visit opens up a tier of treatments that simply aren’t available over the counter.
What Happens at Your First Visit
Your dermatologist will examine your skin closely, looking at the types of lesions you have (blackheads, whiteheads, red bumps, deep cysts), where they cluster on your face and body, and whether you already have scarring. They’ll ask about your history with acne, what you’ve already tried, your menstrual cycle if relevant, and any medications you take. This assessment determines your acne grade, from mild comedonal acne to severe nodular or cystic acne, which drives every treatment decision that follows.
Prescription Topicals
For mild to moderate acne, a dermatologist will typically start with topical prescriptions that work differently than anything you can buy at a drugstore. The biggest category is retinoids: medications like tretinoin, adapalene, and tazarotene that speed up skin cell turnover, unclog pores, and prevent new breakouts from forming. While a low-strength adapalene gel is now available over the counter, prescription versions come in higher concentrations and additional formulations that allow your dermatologist to fine-tune the strength to your skin’s tolerance.
Topical antibiotics are another common prescription. Clindamycin and erythromycin kill acne-causing bacteria and reduce inflammation directly at the skin’s surface. Dermatologists almost always pair these with benzoyl peroxide to prevent antibiotic resistance, and combination gels that contain both ingredients in a single tube make this easier. Azelaic acid, a prescription cream that reduces bacteria and calms redness, is another option particularly useful for people with sensitive skin or darker skin tones prone to post-acne dark spots.
The key difference between these prescriptions and drugstore products like salicylic acid washes or benzoyl peroxide spot treatments is potency and mechanism. Retinoids reshape how your skin behaves at a cellular level. Topical antibiotics target inflammation that no OTC product can match. Your dermatologist will often combine two or three of these into a single regimen, attacking acne through multiple pathways at once.
Oral Medications for Moderate to Severe Acne
When topicals alone aren’t enough, dermatologists add oral medications. The most common first step is an antibiotic, usually doxycycline or minocycline. These are prescribed for moderate to severe inflammatory acne and for cases where topical treatments haven’t worked. The goal is to knock down widespread inflammation quickly, then taper off the antibiotic while maintaining results with topicals alone. Most dermatologists limit oral antibiotics to three to six months to reduce the risk of resistance.
Hormonal Treatments
For women whose acne flares along the jawline, chin, or lower face, especially around their period, hormonal therapy can be highly effective. Combined oral contraceptives containing estrogen are a standard recommendation for inflammatory acne in women. Spironolactone, a medication that blocks the effects of androgens on oil glands, is another option. In a review of 85 women taking spironolactone, one-third had complete clearing and another third saw noticeably less acne. Broader studies show improvement ranging from a 50% to 100% reduction in breakouts. Only about 7% of women saw no benefit at all.
Isotretinoin for Severe Acne
Isotretinoin is the most powerful acne medication available. It’s recommended for severe nodular acne, for moderate acne that hasn’t responded to other treatments, and for acne that’s causing scarring or significant emotional distress. A single course, typically lasting five to six months, can produce long-term remission for many patients.
Because isotretinoin can cause serious birth defects, it comes with strict safety requirements through a federal program called iPLEDGE. Anyone who can become pregnant must have a pregnancy test in a medical setting before starting treatment. During treatment, the FDA recently approved changes allowing at-home pregnancy tests if your prescriber permits it, though the first test before your initial dose must still happen in a clinical setting. If you miss your prescription pickup window, you can now repeat a pregnancy test immediately without a waiting period. Patients who cannot become pregnant still receive counseling at enrollment, but monthly documentation of that counseling is no longer required, and there’s no longer a 30-day prescription window. Blood tests to monitor liver function and cholesterol levels are part of the process throughout treatment.
In-Office Procedures
Dermatologists have several tools they can use during your visit that go beyond prescriptions.
Cortisone injections are the go-to for painful cystic breakouts. Your dermatologist injects a small amount of a steroid called triamcinolone directly into the cyst. This can reduce swelling, redness, and pain within a few days, making it one of the fastest acne treatments available. It’s especially useful before events or when a cyst is too deep for topical treatments to reach.
Chemical peels using glycolic acid or salicylic acid remove the outer layer of skin, helping to clear clogged pores and improve skin texture. These are light, superficial peels that cause mild stinging and some redness but minimal downtime. Medium-depth peels using trichloroacetic acid go deeper and are more commonly used for acne scars than active breakouts.
Treating Acne Scars
Many people see a dermatologist not just for active acne but for the scars it leaves behind. Scar treatment is a separate process that usually begins once active breakouts are under control, because treating scars while new ones are still forming is counterproductive.
Subcision is a technique for depressed, pitted scars. Your dermatologist inserts a small needle beneath the scar and moves it to break up the fibrous bands pulling the skin downward. This releases the scar and allows the skin to lift. Most moderate scarring requires three to six sessions spaced at least a month apart. Subcision works best for broader, rolling scars rather than narrow ice-pick scars.
Dermatologists often combine subcision with other techniques for better results. Microneedling, which creates tiny punctures in the skin to stimulate collagen production, can be performed as soon as a day after subcision. Fractional laser treatments resurface the skin by targeting small zones of tissue, triggering the body’s healing response to fill in depressed areas. Chemical peels with trichloroacetic acid, applied directly into individual scars (a technique called TCA CROSS), can raise the base of deep pitted scars over multiple sessions. Topical retinoids used between procedures help maintain collagen remodeling. The best scar treatment plans typically layer several of these approaches rather than relying on any single one.
What to Expect From Treatment Timelines
Acne treatment requires patience. Most prescription topicals take six to eight weeks before you see meaningful improvement, and your skin may look temporarily worse during the first few weeks as clogged pores purge. Oral antibiotics tend to show results faster, often within four to six weeks, but they’re a bridge to longer-term topical maintenance. Hormonal treatments like spironolactone typically need two to three months to reach their full effect. Isotretinoin works progressively over a five-to-six-month course, with many patients experiencing a flare in the first month before steady improvement.
Your dermatologist will schedule follow-up visits, usually every four to eight weeks initially, to assess how your skin is responding and adjust the plan. If one approach isn’t working, they have enough options to pivot. The combination of prescription-strength products, systemic medications, and procedural tools is what makes a dermatologist visit fundamentally different from managing acne on your own.
