The role of emollients in skin hydration
THE ROLE OF EMOLLIENTS IN SKIN HYDRATION
When the top layer of the skin (epidermis) gets dry, it can crack and flake off, leaving open spaces between the cells in the skin.2 Emollients are moisturising treatments that cover the skin with a protective film to reduce this water loss.3,4 Frequent application is needed to replace lost moisture – emollients cannot be overused.4
EMOLLIENTS:3,4
- Are effective in managing dry skin conditions
- May have mild anti-inflammatory properties
- Help to reduce the number of eczema flare-ups
To achieve these functions, emollients may contain:
LIPIDS2,5
These are fatty substances (fats and oils) that fill the open spaces between cells to make the skin smoother and softer.
CERAMIDES6,7
These are fatty acids that may re-establish the balance of fats necessary for the appropriate functioning of the skin barrier. They protect the skin by creating a barrier to prevent moisture from leaving the skin and prevent dryness by locking moisture into the skin. They can also protect the skin from infection.
OATMEAL6,8
Oatmeal and colloidal oatmeal have a soothing, softening effect on the skin. They offer a layer of protection while also having anti-itch and anti-inflammatory properties.
