Moisturisers are not always needed or used. They are most useful for persons with dry skin.
How they act[change | change source]
These are the effects of a moisturiser:
- Occlusives work by forming a thin film on the surface of the skin to prevent loss of moisture.
- Humectants attract water vapor from the air to moisturize the skin.
- Some add deficient materials. These aim to restore natural moisturizing factors on the skin.
