I'm Worried Sick of Prolonged Usage of HQ & I'm Looking for Alternative Treatment in Place of Obagi Nu Derm Treatment?

Asian, 41yrs, lite skin, i was put on Nu derm in Nov.2008 for 5 mo after self-administered Vi peel at home & left w/ PIH, in 2-3 wks, all the PIH dissappeared, since then i've been on a maintenace program 3x a wk. Recently I'm worried sick upon reading articles about side effects of prolonged usage of HQ. considered laser but I'm also afraid that I may end up with worsened PIH after reading horror stories. stop on complete usage of HQ is not ideal then is there any way I can minimize the usage?
