Ceramide NS

Ceramide NS belongs to a larger group of ceramides that are naturally occurring, long chains of lipids (fats) that are major components of skin’s outer layers. In fact, skin’s composition is 50% ceramides.

Ceramide NS in particular is a sphingosine-based ceramide, which when included in skin care formulas, helps skin produce more of its own ceramides. This helps skin better retain its moisture, while simultaneously strengthening its barrier against external stimuli.

In general, ceramides work best when they’re combined with other replenishing ingredients like fatty acids and cholesterol. These lipid mixtures work in multiple ways to improve skin’s texture, suppleness, and help calm signs of sensitivity. Indeed, ceramides play a critical role in maintaining healthy skin.

Ceramide NS can be derived from various sources both synthetic and natural, including yeast.

The Cosmetic Ingredient Review Expert Panel’s 2020 assessment concluded that ceramide ingredients are safe in cosmetics in the present practices of use. Their survey data looked at personal care products containing concentrations between 0.001-0.006% of ceramide NS. This is a good example of how a seemingly low concentration of an ingredient can still have a noticeable effect on skin.
