continuous use of the products u are using can only be advised if the doc feels that the benefits are more than the side-effects
and there is nothing that u have to use only these products for so long
chemical peeling is not the mainstay of treatment of acne
but retionoids are
and how to be used and for how long can be determinded by dermat only
bengel need not be given for so long, it can be avoided if the dermat feels.
to reduce the acne marks and pore size u might have to use topical and/or oral retinoids
for long duration as suggested by dermat
