Stratum corneum, a layer of skin, needs to consist of between 20 and 30 per cent water. Having a much lower water content than this results in reduced skin elasticity and surface roughness, the report added.
But researchers found no scientific proof to confirm that drinking lots of water actually helps plump up and hydrate the skin and improve its appearance.
"In light of the popular belief that water does indeed benefit skin health, there is an obvious need for more research in this area," the report adds.
