Article
Ceramide EOS (formerly known as ceramide 1) belongs to a larger group of ceramides that are found naturally in skin as long chains of lipids (fats). The “EO” refers to the type of fatty acid correlated with the ingredient and “S” stands for this ceramide’s sphinogsine base.
Healthy skin is made up of 50% ceramides, but when those ceramides decrease, skin’s barrier becomes weaker, making it more vulnerable to external stressors and dehydration. As a skin care ingredient, topical application of ceramide EOS can step in to help fill this gap and replenish skin’s barrier, so it is better able to defend itself from external stimuli.
Ceramide EOS works best when combined with other ceramides + replenishing ingredients like fatty acids and cholesterol. Together, these lipid mixtures improve skin’s hydration, resiliency, and suppleness. They also play a signaling role in maintaining healthy skin.
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 up to 0.01% of ceramide EOS. Ceramides used in skin care can be synthetic (aka lab engineered) or sourced naturally from plants.
