My 5 year old granddaughter has dry skin and little white bumps all over - what causes this and is there a cure?

Its probably moloscums I have them you just leave them and they will go away in years to come if you are worring too much go and see her docter

If it is molluscum contagiosum, which is a self-limiting but long-lasting viral infection, you may look for a cure for it in the alternative therapies, which do have some remedies to offer.
