I have not had this problem. Are you taking the Omega 3 supplements? I had dry skin when I first started the diet, and up'ed my Omegas... I take 3 1000mg Flaxseed capsules (allergic to shellfish) each day, and I have also added CLA and GLA, which are lesser known essential fatty acids. Now my skin is happy.
This happens because the diet is so low in fat, as we only get 2 teaspoons of olive oil each day. You could also up the olive oil a little, but that might slow down your weight loss.
Here is an article the discusses omegas and dry eyes... worth a try.
