I'm using La Roche Posay Effaclar H "designed for oily skin made fragile by over-drying skincare" - sounded like exactly what I wanted and I'd highly recommend. It is non comedogenic and for sensitive skin and is tested on acne prone skin. It feels nice on and absorbs well so although I use it at night you could use it during the day too if you wanted. (I use a moisturiser with spf in the day - same brand.)

I'm in the same boat, about to start using Duac and was wondering about a moisturizer to use with it. In the past I've given up on prescription creams and gels because the dryness and redness are way too much to handle.

Cerave is working well for me. Cetaphil made me break out even more.
