A dermatologist will examine your skin, classify the type and severity of your acne, and build a treatment plan tailored to what’s driving your breakouts. That plan typically combines prescription topicals, possibly oral medications, and sometimes in-office procedures. What you’re prescribed depends largely on whether your acne is mostly blackheads and whiteheads, inflamed red bumps, or deep painful cysts.
What Happens at the First Appointment
Your first visit starts with a medical history. Expect questions about your family history of skin conditions, any medications you’re currently taking, your skincare routine, diet, stress levels, and how long you’ve been dealing with breakouts. If you’ve tried over-the-counter products or previous prescriptions, mention those too, since it helps your dermatologist understand what hasn’t worked.
Next comes the physical exam. Your dermatologist will closely inspect your skin, sometimes using a small magnifying device called a dermatoscope, looking at the types of lesions present, where they’re located, and whether there’s any scarring. They’re categorizing your acne into a rough severity grade. Grade 1 is the mildest: mostly blackheads and whiteheads with the occasional small bump, confined to the face. Grade 2 adds more inflamed bumps and some pus-filled spots. Grade 3 involves larger inflammatory lesions, pustules, and possibly a few cysts spreading beyond the face. Grade 4 is the most severe, with deep cysts that merge together, abscesses, and widespread scarring, often affecting the chest and back as well.
This grading directly shapes the treatment plan. After the exam, your dermatologist will walk you through their findings and recommend a combination of therapies. Most people leave that first appointment with at least one prescription and a timeline for a follow-up visit.
Prescription Topicals
For mild to moderate acne, topical prescriptions are the foundation. The American Academy of Dermatology recommends using products that combine multiple mechanisms of action, meaning you’ll likely get more than one topical to use together.
Retinoids are one of the most common prescriptions. These are vitamin A derivatives (tretinoin and tazarotene are the most widely used) that speed up skin cell turnover, preventing dead cells from clogging pores. They come in various strengths. Your dermatologist will usually start you on a lower concentration to minimize irritation, then increase if your skin tolerates it well. Retinoids can cause peeling and dryness in the first few weeks, which is normal.
Benzoyl peroxide is another staple. It kills acne-causing bacteria and has a mild pore-clearing effect. It’s often combined with a topical antibiotic like clindamycin in a single gel. The antibiotic directly reduces bacteria on the skin, while the benzoyl peroxide prevents those bacteria from developing resistance to the antibiotic. This combination is prescribed specifically because antibiotics alone can lose effectiveness over time. Other topical options include azelaic acid, salicylic acid, and clascoterone, a newer prescription that blocks hormonal triggers for acne at the skin’s surface.
Oral Medications for Moderate to Severe Acne
When topicals alone aren’t enough, your dermatologist may add an oral medication. Doxycycline is the most commonly prescribed oral antibiotic for acne. It reduces both bacteria and inflammation from the inside out. To limit the risk of antibiotic resistance, dermatologists prescribe these for the shortest effective window, typically three to four months. During that time, you’ll continue using topicals so that when the antibiotic course ends, the topicals can maintain your results.
For women whose acne is driven by hormonal fluctuations, particularly breakouts along the jawline and chin that flare around menstrual cycles, there are two main options. Combined oral contraceptives can help regulate the hormonal shifts that trigger breakouts. Spironolactone, which blocks the effects of androgens (hormones that ramp up oil production), is effective at doses of 50 to 100 mg per day, with some evidence that doses above 100 mg provide additional benefit. It’s only prescribed for women and is not used during pregnancy.
Isotretinoin for Severe or Resistant Acne
If your acne is severe, cystic, or hasn’t responded to other treatments, your dermatologist will likely discuss isotretinoin. This oral medication is the most powerful acne treatment available. It shrinks oil glands, dramatically reduces oil production, and can produce long-lasting remission, often permanently clearing acne after a single course that typically lasts five to six months.
Isotretinoin requires close monitoring. It can cause birth defects, so anyone who can become pregnant must be enrolled in a federal safety program called iPLEDGE. This requires a pregnancy test in a medical setting before starting treatment, with regular pregnancy tests continuing throughout the course. Prescriptions must be picked up within a seven-day window, and if that window is missed, a new pregnancy test is required. Blood work is also drawn periodically to monitor liver function and cholesterol levels, since the medication can affect both. Side effects like dry skin, dry lips, and joint aches are common but manageable. Your dermatologist will discuss all of this in detail before starting you on it.
In-Office Procedures
Beyond prescriptions, dermatologists offer several procedures that can accelerate results or address stubborn spots.
Comedone extractions are one of the simplest. Your dermatologist uses a small sterile tool to manually clear clogged pores, particularly deep blackheads and closed whiteheads that topicals haven’t resolved. This isn’t the same as popping a pimple at home. Doing it in a clinical setting with proper technique minimizes the risk of scarring and infection.
Corticosteroid injections are used for individual large, painful cysts. A small amount of anti-inflammatory medication is injected directly into the cyst, and it can flatten noticeably within 24 to 48 hours. This is especially useful before an event or when a cyst is causing significant pain.
Chemical peels use acids applied to the skin to remove the outermost layers, unclog pores, and reduce discoloration from old breakouts. Light peels typically use glycolic acid or salicylic acid and involve minimal downtime. Medium-depth peels use trichloroacetic acid, sometimes combined with glycolic acid, and require a few days of peeling and recovery. Your dermatologist will choose the type based on your skin tone, sensitivity, and what they’re trying to accomplish.
Light and Laser Therapy
Photodynamic therapy (PDT) is an option some dermatologists offer for inflammatory acne that hasn’t responded well to conventional treatments. It involves applying a light-sensitizing solution to the skin, then exposing it to a specific wavelength of light that targets acne-causing bacteria and overactive oil glands.
Clinical results vary, but studies show meaningful reductions in inflammatory lesions. In one trial, two treatments given two weeks apart produced a 68% reduction in inflammatory acne 12 weeks later. Another study found a 54% reduction compared to 20% in a control group over the same period. Most courses involve two to four sessions spread over four to eight weeks. PDT isn’t a first-line treatment, and it can cause temporary redness and peeling, but it’s an option worth discussing if standard therapies have plateaued.
What a Typical Treatment Timeline Looks Like
Acne treatment is not fast. Most topical prescriptions take six to eight weeks before you see noticeable improvement, and full results can take three to four months. During the first few weeks, some people experience a “purging” phase where acne temporarily worsens as clogged pores come to the surface. This is particularly common with retinoids and is actually a sign the medication is working.
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 a topical combination isn’t producing results after a few months, that’s when they may escalate to oral medications or switch strategies. Treatment is iterative. Your dermatologist expects to refine the approach based on how your skin responds, so being honest at follow-ups about what’s working and what’s causing side effects makes a real difference in how quickly you get to clear skin.
