Besides humectants such as glycerin, propylene glycol or PCA, actives like hyaluronic acid or natural ester oils (e.g. MIGLYOL® 8810 ECO) can help to increase skin hydration. The effectiveness can be measured with a corneometer (read more in our article: “MIGLYOL® 8810 ECO – The water-light Feel-Good-Emollient goes green“).
Here slugging comes into play to keep the moisture in the skin. Slugging has nothing to do with snails; however, the interpretation of leaving a “slime trail” fits the topic. The idea is to prevent moisture loss (TEWL) from the skin with a thick layer of petroleum jelly as the final step in the Skin Care Night Time Routine, thus restoring the skin barrier overnight. The result is smooth, glowing skin the next morning. In addition to Vaseline, other film-forming ingredients such as lanolin, SOFTISAN® 649 or even the liquid MIGLYOL® 829 ECO are also suitable for “slugging”. You can read more about the properties of SOFTISAN® 649 in the article: SOFTISAN® 649 – A cocooning Shield for Skin and Hair in Wintry Weather.
Ceramides or squalane, which are part of the stratum corneum (Human stratum corneum lipids: characterization and regional variations – ScienceDirect), can also be added to further support the suppleness of the skin. Natural oils with a high content of linoleic acid, such as evening primrose oil, safflower oil or grape seed oil, are also known to gently strengthen the skin barrier. And natural ester oils such as MIGLYOL® Coco 810 can provide soft, nourished and moisturized skin too, thanks to their structure and emollient effect.
The combination of moisturizing, film-forming and softening ingredients, along with a healthy lifestyle that includes drinking plenty of water and avoiding aggressors such as too strong physical or chemical peelings or UV radiation, can lead to a strengthened skin barrier.
