Accutane may be working when your skin feels less oily, your hair gets less greasy, and new breakouts become smaller, fewer, or less inflamed. Early dryness, especially dry lips, can also appear before major acne clearing because isotretinoin lowers oil production. The signs that Accutane is working often appear within 4 to 6 weeks, but fuller, more stable improvement typically takes 4 to 5 months of treatment.
Progress can look uneven at first, and some patients may flare before they improve. A good early sign is not perfect skin, but a slower acne cycle with fewer painful cysts, less swelling, and reduced oil. Your dermatologist can help you review your timeline if acne continues to worsen after the initial adjustment period.
