Im taking accutane 10mg 2x/day a total of 20mg. am a male 120 lbs 5'6 height. currently on my 27th day. am just wondering if low a dose effective?

Low dose: You must be on first month. The low dose is effective. Best chance for permanent cure is a much higher dose for 5 months or continue the small dose for a much longer time. Usually the starting dose is small because it is better tolerated, then increased every month if tolerated. You will improve in 1-3 months. Probably you will be clear by 5 months. Sounds like you have a good dr.
