Just make sure that you're thoroughly massaging the cleanser over your entire face because there really isn't any set time length that you need to massage it into your face.
The properties of the cleanser should do all the work. So, There may be a certain length of time that you should leave the cleanser on your face, and if there is it will be written on the bottle.
If you're not noticing any results, it could be because your pore are so clogged up that you need to have them extracted!!!! So think about making an appointment to get a facial.
