Judging from the ingredient list, "Olay - Complete Moisturiser Fluid Normal/Oily" works well for improving skin hydration To work well, any moisturizer needs to include a combination of water-binding and emollient ingredients. Olay - Complete Moisturiser Fluid Normal/Oily ticks this box. Panthenol and glycerin in this product (humectants) attract water molecules to the upper layer of the skin (the water comes from the outside air or from the deeper layers of the skin if the air is dry). Dimethicone, dimethiconol, cetearyl alcohol, cetyl alcohol and isopropyl palmitate in this product help decrease the water evoporation from the skin, so that it stays hydrated for longer. These ingredients also soften the skin and take away the feeling of tightness and dryness.
