Based on the ingredients included, "No7 - Essential Moisture Day Fluid" works well for moisturizing the skin. To work well, any moisturizer needs to include a combination of water-binding and emollient ingredients. No7 - Essential Moisture Day Fluid ticks this box. Glycerin and butylene glycol 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). Petrolatum, isopropyl myristate, oenothera biennis oil, theobroma cacao seed butter and dimethicone 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.

This product can help improve hydration of the skin with the two types of ingredients.
The first type is called “humectants”: these ingredients help attract water.
When humectants are on the surface of the skin, they “pull in” the moisture from the outside environment, or from
within deeper layers of the skin. The following ingredients in this product do the job:
glycerin, butylene glycol.
This product also contains ingredients called “occlusives”. They help reduce the speed with which our skin loses
moisture to the outside environment. These ingredients also help soften the upper layer of the skin, so it feels
less tight and nicer to the touch. The following ingredients in this product do the job:
dimethicone, isopropyl myristate.
The following ingredients in this product are especially good for supporting the skin barrier and helping with
the hydration level: petrolatum
A silicone that helps to reduce water loss from the surface of the skin. Can temporarily "fill in" lines and wrinkles, absorb oil, and create a nice product finish
