By the third month of isotretinoin treatment, some patients start to see fewer active breakouts, less oiliness, and calmer inflammation, but results can still vary. During Accutane month 3, it is still possible to have new pimples, purging, red marks, or slower progress, especially with severe or cystic acne.
Common side effects, such as dry lips, dry skin, dry eyes, nosebleeds, sun sensitivity, and joint or muscle discomfort, may persist during this stage.
