Ceramides
Lipid molecules naturally present in the stratum corneum
Function in skin biology
Ceramides are a family of lipid molecules that make up a significant proportion of the stratum corneum's intercellular lipid matrix. Alongside cholesterol and free fatty acids, ceramides form the structural lipid bilayers that hold skin cells together and contribute to the barrier's ability to retain water and resist environmental stressors. Skin with reduced ceramide content is more frequently associated with dryness and a compromised-feeling barrier.
Why Ambernay uses it
Ambernay includes ceramides where the formula objective is to support barrier integrity and intercellular cohesion — they are a structural contributor rather than a single-effect active. Synthetic, biomimetic ceramides (matching the ratios found in human skin) are used to support compatibility and consistency between formula batches.
Where concentration matters
Cosmetic research has evaluated ceramide-containing formulas at total ceramide concentrations typically between 0.1% and 2%, often combined with cholesterol and fatty acids in ratios that approximate the skin's natural lipid composition. The ratio between lipid types is considered as important as the total concentration.
What we do not claim
We do not claim that ceramides repair barrier damage, treat eczema, dermatitis or any other skin condition. Ceramides in a cosmetic formula are evaluated as structural lipid contributors — not as a pharmaceutical intervention.
Used in Ambernay products
- Hydra-Rich Moisturizer — barrier structure context
- Hydra-Calm Moisturizer — barrier structure context
Best paired with
Ceramides are typically formulated alongside cholesterol and fatty acids (the "barrier lipid trio"), and pair well with humectants such as glycerin and panthenol for a complete hydration architecture.
Claim caution / regulatory note
Ceramides are cosmetic lipid ingredients. Claims must remain within cosmetic function: barrier feel, intercellular cohesion, visible dryness reduction. Medical or disease-treatment claims are not permitted in a cosmetic context.
