Many people have dry skin. In general, this is due to the disruption of the functioning of the hydrolipid barrier, which protects the skin from water loss. How to rebuild the hydrolipid barrier?

What to apply to dry skin of the face (e.g. serum with aloe vera, cream with allantoin) and body (e.g. linseed oil)? Does drinking water moisturize the skin?
