Discouraged.. Cystic acne chin only on spironolactone 100 mg die since 3 months: increase spironolactone or take accutane?

32 years old, known for papulopustular Rosacea since one year well controlled with rosiver. I developed 6 months ago cystic acne on chin only.. I started spironolactone 100 mg die 3 months ago with a clearance of 80% of comedones and less cysts.. (1 cyst each two weeks instead of 2-3 cysts/week) without secondary effects. This week I developed 3 cysts in a row... Is it safe and effective to increase to 150 mg die of spironolactone or should I take accutane?
