Does low dose accutane actually work? I am 32 years old and have recently started struggling with my skin.

I am 32 years old and have recently started struggling with my skin. My GP suggested a low dose (10mg) of accutane x2 a week since I only have mild acne. We have tried other treatments before including a topical antibiotic which worked initially but then stopped. I am anxious about trying accutane after reading about side effects however I would really like to get rid of my adult acne. How long would I need to be on this treatment to see lasting results? Thank you!
