What kind of hand cream do you use afterward? It should be a good, strong medical cream. :) There are components in such gypsum investment that have a rather bad effect on the skin. But it looks like dermatitis won't scare you.
In any case, other people should understand that it is better not to get into the investment mixture with such bare hands.
