Question:
i use the normal hydra zen and when my pot empties i will get the neurocalm.. its basically a little different fragrance wise, has some more water in it i think and prob some new ingredients. its just an updated version of the current HydraZen.
You can get a HydraZen for normal skin.. or for dry skin. in your case.. just buy the creme for normal skin as the dry skin cream is alot thicker.

Answer:
Cool, thanks for that. Do you know whether there is a big diff between the night and day ones? Because I want one to use at night but I dont want it to be too heavy
