How can I fight dry skin?

I am using the Daniel Kern face regimen, the AHA+ lotion and the Treatment. The treatment is making my face dry out really bad, but it is the most important one for me to use, it does most of the work I can't stop using it. I have tried so many things to prevent my face from drying out, and none of it works! The actual face wash I use is a generic oil-free acne wash, I'm not sure if that is just making my face even worse or not but I've been using it for a long time and just in the past 7 or 8 months has my face been getting really dry. If anyone has any suggestions or anything else I could try that would really help. I know this is kind of a weird subject to ask complete strangers about, but I'm desperate!!! Also if you could give me some names of face wash for sensitive skin that would help also. Thank you so much!!!!!
