Discussions that mention benzaclin

Acne board

I read that using other topical meds with tretinoin can actually negate the effects of the tretinoin, but then I keep reading about people who use retin-a at night and another topical in the am, for example.

Can anyone clarify what can be used in combo with tretinoin and how? I want use tretinoin .025% every other day. I'd like to use benzaclin on the off-days, but I don't want to cause the tretinoin to not work. I've read that people do this though, and they don't seem to have a problem.

Also, does using moisturizer immediately after applying tretinoin cause any problems? Should I wait, or only moisturize in the morning?

Any help would be greatly appreciated. Thanks!
