Similar story here. I also seem to have got my skin more under control with Duac. I'd seen various GPs about it but Duac was never mentioned. It took a fantastic beautician I saw for a facial to suggest asking for a prescription. Worth trying if you haven't already?
I have a tendency towards dry patches and redness so I'm very wary of anything with benzoyl peroxide in it. I had some in my teens for spots and it dried out the spot but also almost burnt my skin. Oh and I got sunburnt while using it on a fairly cloudy day in Newcastle!
The derma flannel looks interesting but might be a but harsh after I checked out a MN thread about it.
I did the OCM last night (I do it occasionally) and my skin feels nicer so maybe I should do that more often. I tend not to cleanse that often as my skin gets dried out easily.
