2-Hydroxy Lignoceroyl Phytosphingosine (Ceramide AP C24)
INCI name · 2-Hydroxy Lignoceroyl Phytosphingosine
In short
An alpha‑hydroxy C24 ceramide that enhances cohesion within the skin’s lipid layers. It helps reinforce barrier comfort and moisture retention.
What it is
α-Hydroxylated C24 ceramide AP-type with phytosphingosine backbone; the 2-OH group on the acyl chain enables additional hydrogen bonding with adjacent headgroups in the lamellar bilayer, strengthening cohesion; alpha-hydroxy ceramides constitute roughly 5-10% of total stratum corneum ceramide content and are particularly important in the ceramide AP and EOP subtypes.
