LYSOPHOSPHATIDIC ACID.

Valuable / HAIR CONDITIONING, SKIN CONDITIONING

Lysophosphatidic Acid (LPA) is a potent, naturally occurring lipid signaling molecule vital for skin health. It actively promotes robust skin barrier function and significantly enhances hydration through targeted cellular mechanisms.

Science

Mechanism of Action

Lysophosphatidic Acid (LPA) modulates skin function by engaging LPAR1 and LPAR5 receptors on keratinocytes. This interaction activates the RHO-ROCK-SRF pathway, upregulating filaggrin (FLG) expression crucial for barrier integrity and facilitating keratinocyte differentiation. LPA also increases profilaggrin and serine palmitoyltransferase (SPT) mRNA expression via Ca2+ influx modulation, enhancing skin moisturization and barrier strength. Sodium cyclic lysophosphatidic acid (NcPA), a specific LPA variant, further boosts skin moisture by stimulating hyaluronic acid synthesis. Additionally, LPA influences keratinocyte proliferation, differentiation, and broader skin repair processes through various complex signaling pathways.

Stability

Lysophosphatidic Acid (LPA) is a dynamic molecule whose content can vary with storage conditions and in the presence of certain chemicals. For analytical purposes, concentrated stock solutions are stable at -80°C for 6 months or -20°C for 1 month, with fresh preparation recommended for working solutions. Heat and/or sonication can assist dissolution if precipitation occurs. Optimal pH range for cosmetic formulation stability is not specified in current research.
