How long do u keep the acne treatment on for skinID?

do u keep it on over night. its not a wask its an acne treatment. it doesnt say how long.|||What I do is I put my treatment on before i got to bed and wait maybe 15 min before i go sleep with it on. I just wash it off in the morning. I%26#039;ve been doing that for the past 4 years with many different products and its always worked. My brother does the same thing.|||You leave it on until the next time you wash your face. Wash your face in the morning and at night before you go to bed.|||i think you just wash you face with it then put on the lotion|||well first of all,.. whats the treatment called? second, look at the directions.
