Accutane
Accutane (isotretinoin) is an oral retinoid used for severe, treatment-resistant nodular acne. It's taken as a daily capsule dosed by body weight for roughly 15 to 20 weeks. It's the only oral medication known to induce long-term remission of severe acne.
Differin

Accutane vs. Differin Pros and Cons
Accutane
Accutane offers the possibility of long-term remission from severe acne after a single course, something no topical treatment can achieve. It requires strict monitoring, including monthly pregnancy tests and bloodwork, and carries serious risks that limit who can safely use it.
Pros
Can induce long-term remission after one course
Effective for cases that fail antibiotics and topicals
Fixed treatment course, typically under 6 months
Cons
Boxed warning for severe birth defects
Requires iPLEDGE enrollment and monthly monitoring
Risk of depression and suicidal ideation
Roughly $200 to $500 per month without insurance
Differin
Differin treats acne directly at the skin without systemic risk, making it accessible and easy to start. It requires ongoing daily use to maintain results and generally works more slowly than isotretinoin for severe cases.
Pros
Available over the counter at 0.1% strength
No boxed warning or systemic monitoring needed
Roughly $14 to $76 per month without insurance
Cons
Not effective for severe nodular acne
Requires indefinite daily application to maintain results
Common local skin irritation and sun sensitivity
Slower results than oral isotretinoin
