Ceramide NP – Premium Skin Barrier Lipid | AIHerba® Natural Cosmetic Ingredient Supplier
High-Purity Ceramide NP for Cosmetics, Functional Skincare & Dermatological Formulations
(1) Product Overview
Ceramide NP (also known as Ceramide 3) is a bioidentical skin lipid naturally found in the stratum corneum of human skin. It plays a critical role in maintaining the skin barrier, preventing transepidermal water loss (TEWL), and protecting against environmental damage. AIHerba® offers high-purity, cosmetic-grade Ceramide NP produced through advanced biotechnology fermentation and molecular purification, ensuring excellent stability, biocompatibility, and efficacy.

(2) Botanical Source & Production
Although ceramides are naturally present in plant oils and human skin, AIHerba® Ceramide NP is synthesized through microbial fermentation and enzymatic conversion of plant-derived sphingolipids, ensuring vegan, non-GMO, and eco-friendly purity.
Production Process:
-
Raw Material Preparation – Plant sphingolipids derived from wheat, rice bran, or soybeans.
-
Fermentation – Controlled microbial process to generate sphingoid bases.
-
Purification – Molecular distillation and chromatography for high-purity ceramide isolation.
-
Stabilization – Encapsulation or micronization for enhanced bioavailability and cosmetic compatibility.
-
Quality Testing – Each batch undergoes full-spectrum quality evaluation and COA verification.

(6) Traditional & Scientific Background
Ceramides were first identified as key lipids in the skin’s stratum corneum, representing nearly 50% of the intercellular lipid matrix. Modern research confirms their essential role in maintaining the epidermal barrier and moisture balance (PubMed: PMID 11534942).
Studies published by the NIH and FDA-reviewed literature support ceramide supplementation for improving skin hydration and barrier recovery.
