Could coffee/caffeine cause serious dryness in skin?

Lately, I drink about 3-4 glasses of coffee daily. I just started drinking coffee recently, so, I have never drank this much coffee in a daily basis before. However, I started to notice that my skin is seriously dry especially on my face, hand and feet. Quite serious that it starts to get itch, crackling and red. I decided to put more moisturizer but it did not seem to help. I also living in a air-conditioned room all the time. Is it the AC or the caffeine that cause the dryness?
