After one year on Accutane, most patients achieve between 80 and 95 percent clearance of their acne, with many experiencing complete remission that lasts for years or even permanently. The transformation is often dramatic””someone who started treatment with severe nodular acne covering their cheeks, jawline, and back may find themselves with clear skin and only occasional minor breakouts, if any.
A typical patient finishing a standard six-month course and reaching the one-year mark post-treatment will have seen their oil production normalize, active lesions resolve, and scarring begin to fade, though the timeline varies based on cumulative dosage, acne severity, and individual response. This article covers the realistic month-by-month progression you can expect during and after Accutane treatment, including the infamous initial purging phase, when results typically stabilize, what happens if acne returns, and the long-term side effects that may persist beyond your treatment course. Understanding these benchmarks helps set appropriate expectations and recognize whether your progress falls within normal parameters.

What Does Typical Accutane Progress Look Like After 1 Year?
The one-year mark usually falls several months after completing a standard accutane course, which typically runs five to seven months depending on weight-based dosing and response. By this point, isotretinoin has fundamentally altered the sebaceous glands, shrinking them by up to 90 percent and reducing sebum production dramatically. For most patients, this means the oily skin that once required blotting papers every few hours has been replaced by normal or even dry skin that may need regular moisturizing. Progress isn’t linear, and the one-year snapshot looks different depending on when treatment ended. Someone who finished their course eight months ago will likely have stable, clear skin with any post-inflammatory hyperpigmentation continuing to fade naturally.
In contrast, someone still in their final months of an extended course may be seeing the last of their lesions resolve while managing ongoing dryness and sensitivity. A 22-year-old with moderate cystic acne, for example, might reach the one-year point with completely clear skin and only faint pink marks where deep cysts once sat, while their oil production has returned to a moderate level that keeps skin healthy without causing breakouts. The durability of results at one year is encouraging. Studies show that approximately 60 percent of patients remain completely clear after a single course, while another 30 percent experience significantly reduced acne that responds well to topical treatments alone. Only about 10 to 20 percent require a second course of isotretinoin.
The Month-by-Month Timeline During Treatment
Understanding what happens during the treatment months provides context for where you should be at the one-year mark. The first month typically involves the dreaded “purge,” where existing microcomedones are pushed to the surface, temporarily worsening acne. This phase discourages many patients, but it’s a normal part of the process that indicates the medication is working. Someone with primarily comedonal acne may see dozens of whiteheads emerge in weeks two through four. Months two through four generally show the most dramatic visible improvement.
Active inflammation decreases noticeably, new cysts become rare, and existing lesions begin healing. By month three, many patients report that they’ve stopped developing new pimples entirely, though residual marks from previous breakouts remain. The skin also becomes progressively drier during this phase, often requiring significant adjustments to skincare routines. Months five through seven, for those on longer courses, involve refinement rather than dramatic change. The skin continues to heal, texture improves, and the cumulative dose approaches the target of 120 to 150 milligrams per kilogram of body weight that research suggests provides optimal long-term remission. However, if you’re still experiencing significant breakouts in month five, your dermatologist may extend treatment or investigate other contributing factors like hormonal imbalances or medication absorption issues.
Why Some Patients See Results Faster Than Others
Individual variation in Accutane response is substantial and depends on several factors beyond anyone’s control. Acne severity at baseline matters significantly””someone with mild-to-moderate inflammatory acne will typically clear faster than someone with severe nodulocystic acne, though the latter often sees the most life-changing results by the one-year mark. A patient starting with grade II acne might achieve near-complete clearance by month three, while someone with grade IV acne may need the full six or seven months before seeing similar results. Dosing strategy also affects the timeline. Higher doses (closer to 1 mg/kg/day) typically produce faster results but come with more intense side effects.
Lower doses taken over longer periods may be equally effective for long-term remission while being more tolerable, but the visual improvement happens more gradually. Some dermatologists now prefer low-dose protocols of 0.25 to 0.5 mg/kg/day for patients with moderate acne or those prone to side effects, accepting a longer treatment duration for better tolerability. Absorption variables create another layer of unpredictability. Isotretinoin is fat-soluble and absorbs significantly better when taken with a meal containing at least 20 grams of fat. Patients who consistently take their medication with high-fat meals may see faster progress than those who take it on an empty stomach or with low-fat foods. This explains why some patients plateau despite good compliance””they may simply not be absorbing the medication efficiently.
Managing Side Effects That Persist at One Year
While most Accutane side effects resolve within weeks to months of completing treatment, some patients experience lingering effects at the one-year mark. Dry lips are nearly universal during treatment but typically resolve within one to three months of stopping. Persistent dryness beyond this point is uncommon but does occur, usually in patients who were predisposed to dry skin conditions. A 28-year-old who completed her course nine months ago, for instance, might find that her lips still require more maintenance than before treatment, though nothing close to the intense dryness during active treatment. Joint and muscle pain, reported by roughly 15 to 20 percent of patients during treatment, almost always resolves after discontinuation. However, a small subset of patients””estimates suggest fewer than one percent””report persistent musculoskeletal symptoms.
These cases are controversial in the medical literature, with some researchers questioning whether the association is causal or coincidental. If you’re experiencing ongoing joint pain at the one-year mark, a thorough evaluation for other causes is warranted. The psychological side effects remain the most debated aspect of isotretinoin. While large-scale studies have not established a clear causal link between Accutane and depression, individual reports of mood changes persist. At one year, any treatment-related mood effects should have long resolved. If you’re still experiencing depression or anxiety, these symptoms deserve evaluation independent of your Accutane history, as the medication is unlikely to be the ongoing cause.
What Happens If Acne Returns Before the One-Year Mark
Relapse within the first year after completing Accutane occurs in a minority of patients but can be deeply frustrating. Early relapse””within three to six months of stopping””sometimes indicates that the cumulative dose was insufficient or that an underlying hormonal condition is driving persistent acne. Women with polycystic ovary syndrome, for example, have higher relapse rates because the hormonal component of their acne wasn’t addressed by isotretinoin alone. The severity of relapse matters when determining next steps. Mild breakouts that respond to topical retinoids or benzoyl peroxide don’t necessarily warrant a second Accutane course.
Many dermatologists recommend trying topical maintenance therapy first, as the skin is often more responsive to these treatments after isotretinoin has reset the sebaceous glands. Only when moderate-to-severe acne returns despite topical intervention does a second course become the preferred option. A second course of Accutane, if needed, tends to be just as effective as the first. Research suggests that about 70 percent of patients who relapse and undergo a second course achieve long-term remission afterward. The timing of a second course varies””some dermatologists prefer to wait at least four to six months after the first course to confirm the relapse pattern, while others initiate treatment sooner for patients with rapidly worsening acne.
Skin Care Adjustments After Treatment Ends
The skincare routine that worked during Accutane treatment often needs significant modification by the one-year mark. During treatment, most patients abandon active ingredients like retinoids, alpha hydroxy acids, and benzoyl peroxide due to heightened sensitivity. Reintroducing these products too quickly after stopping can cause irritation, but waiting too long misses an opportunity to maintain results. Most dermatologists recommend restarting topical retinoids””the gold standard for acne maintenance””about one to three months after completing isotretinoin.
Beginning with a low concentration two to three times weekly and gradually increasing frequency allows the skin to readjust without excessive irritation. By the one-year mark, many former Accutane patients have successfully incorporated a nightly retinoid into their routine, which helps maintain the clear results achieved during treatment. Sun protection remains important beyond the treatment period. While the acute photosensitivity of isotretinoin resolves within weeks of stopping, the medication may cause long-term changes in how skin responds to UV damage. Additionally, protecting the skin from sun exposure helps post-inflammatory hyperpigmentation and erythema fade faster, improving the cosmetic outcome that patients have worked hard to achieve.
Scarring and Texture: The Longer Game
Acne scars don’t resolve on Accutane’s timeline, and many patients reaching the one-year mark find that while their active acne is gone, textural irregularities and scarring remain. This is normal and expected. Isotretinoin treats active acne but doesn’t directly address established scars””those require separate interventions once the skin has fully healed and stabilized.
The one-year mark is often when dermatologists begin discussing scar treatment options for interested patients. Procedures like fractional laser resurfacing, microneedling, chemical peels, and subcision become appropriate once isotretinoin has been out of the system for at least six months to a year, as the medication impairs wound healing. A patient who completed treatment six months ago might schedule their first fractional CO2 laser session around the one-year anniversary of starting Accutane, beginning the next phase of their skin improvement journey.
Looking Beyond the First Year
For most patients, the period beyond one year represents stability. The dramatic changes are behind them, and maintenance becomes the focus. Annual or biannual dermatology visits can help catch any early signs of relapse and adjust maintenance routines as needed.
The overwhelming majority of patients who remain clear at one year stay clear for the long term, with their Accutane treatment becoming a milestone rather than an ongoing concern. Those who do experience later relapse””sometimes years after treatment””have options. Hormonal therapies like spironolactone for women, maintenance topical retinoids, or a second isotretinoin course can all address recurring acne effectively. The key is addressing relapse early before severe acne and additional scarring develop.
Conclusion
One year after starting Accutane, most patients find themselves in a dramatically different place than where they began. Clear or nearly clear skin, normalized oil production, and freedom from the constant cycle of breakouts represent the typical outcome. While the journey includes challenging phases””the initial purge, persistent dryness, and the patience required for post-inflammatory marks to fade””the end result for most patients justifies the process.
Moving forward, maintaining results requires a thoughtful approach: consistent sunscreen use, a gentle but effective skincare routine that likely includes topical retinoids, and prompt attention to any signs of relapse. For patients concerned about lingering side effects or recurrent acne, open communication with a dermatologist ensures that issues are addressed before they escalate. The one-year mark isn’t an ending but rather a checkpoint confirming that the treatment achieved its goal and establishing a foundation for long-term skin health.
