Is Water a Moisturizer?

Published in Skincare 2 mins read

No, water alone is not a moisturizer. While water hydrates the skin, it evaporates quickly, leaving the skin dry unless a moisturizer is applied to seal in the hydration. Moisturizers work by creating a barrier on the skin's surface, preventing water loss and trapping the moisture from the water you've already applied.

Why Water Isn't Enough

  • Rapid Evaporation: Water evaporates quickly, especially in dry climates or environments with low humidity. This leaves the skin feeling drier than before. [Reference: Reddit ELI5, Healthline, Quora]
  • Lack of Occlusive Properties: Unlike moisturizers, water doesn't possess occlusive properties. This means it can't effectively prevent moisture loss from the skin. [Reference: Reddit ELI5, Quora]
  • Removal of Natural Oils: Frequent washing with water alone can strip the skin of its natural oils, further contributing to dryness. [Reference: Healthline]

How Moisturizers Differ

Moisturizers contain ingredients that help:

  • Attract and Hold Moisture: Some ingredients, like hyaluronic acid, attract and bind water molecules to the skin. [Reference: Peter Thomas Roth]
  • Create a Protective Barrier: Occlusive ingredients like oils and silicones create a barrier on the skin's surface, preventing water loss. [Reference: Tata Harper, Tatcha]
  • Improve Skin Barrier Function: Some moisturizers contain ingredients that strengthen the skin's natural barrier, enhancing its ability to retain moisture. [Reference: Laneige]

Applying a moisturizer to damp skin, not wet skin, allows the moisturizer to better penetrate and effectively hydrate the skin. [Reference: Quora]

It's important to note that while water hydrates, it doesn't moisturize. Moisturizers are necessary to retain that hydration and prevent dryness. Even if you only wash your face with water, a moisturizer is still recommended to maintain healthy skin hydration.
