The skin’s dermis is made up of about 70% of water, which helps to support and hydrate the skin resulting in a healthy appearance. As moisture in the skin decreases (which it will do with age and also affected by environmental factors), the skin becomes dehydrated, leading to surface roughness, flaking, fine lines and much more. You have to help keep your skin hydrated by feeding it with humectants, which attract and hold water molecules making the skin supple and plump.
