Hello AaishaDar,
I suffer from Lupus SLE, MCTD and Sjoegren's Syndrome plus Sicca Syndrome, which are the causes for my dry skin and I have noticed, that air-conditioning in "my" dialysis-center adds very much to my skin dryness.
It helps me a bit to rub after my morning shower some E45 Intense Recovery Body Lotion all over my body and for my face I use some E45 face cream, sometimes I use E45 itch relief cream instead (because this helps more intensively) and/or original Vaseline cream. At first this compilation sounds like a lot of "work", but in reality it only takes a few minutes of my time and it certainly helps a bit. I also make sure that I put on some Vaseline cream in my face before entering the center and that also helps. Why? Because it protects me as much as it possibly can protect from the ultraviolet light and air-conditioning in the center.
Good luck from Kristina and please let us know how you are getting on.
