this is so interesting! i used atralin for about a year with some improvement, but definitely not total improvement...so i've recently switched to retin-a .04. i used atralin in conjunction with aczone and duac and never noticed any negative side effects in terms of peeling/burning/etc...in fact, it may have actually made me more oily but i just assumed it wasn't strong enough for my stubborn clogged pores...will def ask my derm about this!
