Do you just get normally dry like after a shower or is this a constant dryness?
If it's a constant dryness, you could be having an allergic reaction.
If it is indeed an allergic reaction, get some hydrocortosine & glaxal base cream.
Don't use regular lotion as when those evaporate of your skin, it'll make it worse
This is coming from someone who's having a really bad allergic reaction & suffering from dry irratating skin :|
