LYSOPHOSPHATIDYLETHANOLAMINE.

Valuable / SKIN CONDITIONING

Lysophosphatidylethanolamine (LPE) is a key phospholipid celebrated for its significant role in enhancing skin hydration and fortifying the natural skin barrier. It precisely up-regulates vital cellular components to lock in moisture, protect against external stressors, and promote overall skin resilience.

Science

Mechanism of Action

As a crucial phospholipid, Lysophosphatidylethanolamine (LPE) enhances cell membrane fluidity and stability. Its primary mechanism in skin involves up-regulating the expression of mRNAs for key barrier components, specifically profilaggrin, serine palmitoyltransferase (SPT), occludin, and claudin-1. This action strengthens the skin's natural protective barrier and improves its capacity to retain moisture. Due to its amphiphilic structure, LPE effectively interacts with both aqueous and lipid environments. Beyond its barrier-supporting role, it may also contribute to antioxidant and antibacterial activities, soothe irritation, reduce dryness, and enhance overall skin smoothness and resilience. It can also aid in the effective absorption of other active ingredients.

Key findings

  1. 01 A 2011 study indicated that lysophospholipids, including LPE, significantly improve surface water content in human skin. This effect was correlated with increased expression of profilaggrin and serine palmitoyltransferase (SPT) mRNA, alongside stimulated occludin and claudin-1 mRNA and protein levels, suggesting enhanced skin moisturizing capability and barrier function.
  2. 02 In a 2022 study using a human liver-derived cell line (C3A), Lysophosphatidylethanolamine (LysoPE 18:2) demonstrated no cytotoxicity across concentrations up to 200 µM, and notably, showed a slight increase in cell viability. While not directly on skin, this suggests a favorable safety profile at relevant biological concentrations.

Safety Profile

CIR Status
Safe as used
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel deemed Lysophosphatidylethanolamine, along with similar phosphoglycerides, safe for use in cosmetics under current practices and concentrations. The CIR determined that systemic toxicity is not a concern, and any signaling effects are not relevant to its cosmetic application. While a specific maximum concentration for LPE itself is not quantified, the review referenced up to 50% for lecithin in leave-on products and ≤15% for lecithin and hydrogenated lecithin. No specific SCCS opinion or FDA cosmetic status was found; however, the ingredient has received approval from the United States Environmental Protection Agency for agricultural uses.
