not doing anything?
i've been using this for 2-3 weeks and i see no difference. i know you're supposed to wait 6 weeks and see but i'm using this every single night and i'm not even purging in the slightest. i had a breakout before i started using this and the breakout is still there which also shows that the product is doing nothing. i will finish the product to see if anything happens but my assumption is that it's too weak and my skin can take more, since my skin was used to benzyl peroxide twice a day since i was using effaclar duo+ for 3-4 months.
