Acne after Accutane: why it comes back and what a dermatologist may consider

This page is information to help you talk to your dermatologist. It doesn’t give doses or replace their advice.

Does acne come back after Accutane?

For many people, no. The American Academy of Dermatology (AAD) says about 85% of patients see permanent clearing after one course, and its isotretinoin page says clearing is often long-lasting and can be permanent.

But a meaningful minority do relapse. The largest recent study (Lai & Barbieri, JAMA Dermatology 2025) looked at insurance records for 19,907 US patients who completed at least four months of isotretinoin:

• 22.5% relapsed, defined as needing a systemic (by-mouth) acne treatment afterwards
• 8.2% took isotretinoin again

So if your acne has come back, you’re far from alone, and it doesn’t mean the first course “didn’t work”.

Skin Realist check: a couple of spots after finishing isn’t the same as a relapse. Most people still get the odd pimple. What matters is whether acne keeps building over weeks, or deep, painful spots return.

Why does acne come back after isotretinoin?

There isn’t one answer, but research points to a few factors.

Factors linked to relapse

In the 2025 study:

• Total dose mattered. A higher cumulative dose (the total amount taken over the whole course, adjusted for body weight) was linked to lower relapse. The maximum daily dose wasn’t linked to relapse once the total reached conventional levels.
• Women relapsed more often than men.
• Age wasn’t linked to relapse.

This is one reason dermatologists plan a course around a total target rather than only a daily dose. Your dermatologist decides this; don’t change your dose yourself.

Other triggers that still apply

Isotretinoin doesn’t change the things that trigger adult acne. The AAD lists:

• hormone changes around periods, pregnancy, perimenopause, menopause, and starting or stopping birth control
• stress, which increases androgen production
• pore-clogging hair and skin products
• medication side effects
• an undiagnosed medical condition

Is it really acne coming back?

Bumps after isotretinoin aren’t always acne. Things worth ruling out:

• Fungal acne. If the bumps are itchy and all the same size, especially on the forehead, chest or back, they may be Malassezia folliculitis. DermNet lists antibiotic use as a risk factor, and many people take antibiotics before or after isotretinoin. See fungal acne explained.
• Closed comedones. Small, skin-coloured bumps on the forehead are common and respond to a retinoid. See closed comedones.
• Keratosis pilaris (KP). On Reddit, some people say KP “developed after Accutane”. We couldn’t find published reports of isotretinoin causing KP; if anything, dermatologists sometimes use isotretinoin to treat severe KP (Kirchner & Hoyer 2022). If you have new rough bumps, ask your dermatologist.

How do you keep acne away after Accutane?

The AAD says that after skin clears, ongoing treatment is still needed, and most people keep acne away with good skin care and a medicine applied to the skin. Without it, acne can return quickly.

Maintenance with a topical retinoid

A topical retinoid is the usual choice for maintenance. In a small Italian study (Bettoli et al. 2013), 70 patients with moderate to severe acne who had cleared on isotretinoin used adapalene 0.1% plus benzoyl peroxide 2.5% gel once daily for 12 months. Only 2 of the 68 who completed the study relapsed. The study was small and had no comparison group, so it can’t show how many would have relapsed without the gel, but it supports what dermatologists commonly do.

Options include:

• Adapalene 0.1% gel, available without a prescription in the US (Drug Facts)
• Prescription retinoids such as tretinoin, if your dermatologist prefers
• Benzoyl peroxide, often combined with a retinoid

Your skin may still be dry or sensitive after a course, so ask your dermatologist when to start, and begin gently (for example, every other night). See building an acne routine.

Habits that help

• Use non-comedogenic skincare, makeup and hair products.
• Keep a simple routine; don’t stack multiple new actives.
• Note when breakouts happen (cycle, stress, new products), which is useful information for your dermatologist.

What might a dermatologist consider if acne returns?

These are options to discuss, not to choose yourself. Which makes sense depends on how severe the acne is, your history and your preferences.

• Topical treatment first, if the relapse is mild: a retinoid, benzoyl peroxide, or both.
• Hormonal treatment for women: certain birth control pills or spironolactone. The AAD says spironolactone can treat deep, tender acne on the lower face, jawline and neck when other treatments haven’t worked; it requires reliable contraception and isn’t used for acne in men.
• Oral antibiotics combined with a topical treatment, for the shortest effective time (2024 AAD guidelines).
• A second course of isotretinoin. The 2024 guidelines strongly recommend isotretinoin for severe acne, acne causing scarring or psychosocial burden, or acne that hasn’t responded to other treatment. Your dermatologist may also discuss a different dosing plan; the 2025 study suggests the total dose matters more than the daily dose.

A second course involves the same safeguards as the first. The AAD explains that patients are enrolled in the iPLEDGE program, prescriptions cover 30 days at a time with monthly check-ins, and anyone who can become pregnant needs pregnancy tests and must avoid pregnancy. Never buy isotretinoin from websites that don’t require a prescription.

What to bring to your dermatologist

• dates of your previous course(s), and when the acne returned
• photos of the acne now and, if you have them, before your first course
• any side effects you had last time
• everything you’ve used since finishing, and for how long
• for women, any changes to birth control and notes on cycle-related flares
