N-Eicosanoyl Phytosphingosine (Ceramide C20)
INCI name · N-Eicosanoyl Phytosphingosine
In short
N‑Eicosanoyl phytosphingosine is a long‑chain ceramide that supports deep barrier structure and hydration. It helps replenish ceramide levels that contribute to a smoother, more comfortable skin surface.
What it is
Very-long-chain C20 ceramide NP-type; contributes to deep lamellar lipid bilayers in the stratum corneum alongside the predominant C24 ceramide pool; replenishes the longer-chain end of the physiological ceramide distribution which is depleted in dry and eczema-prone skin; phytosphingosine backbone confers additional anti-inflammatory and antimicrobial activity relative to sphingosine-based analogues.
