Science
Mechanism of Action
Nacre lipids operate by modulating key proteins within the epidermis, specifically promoting the overexpression of filaggrin and simultaneously decreasing the expression of transglutaminase. This precise action drives the reconstitution of the intercellular cement of the stratum corneum, effectively repairing the skin's barrier. As essential components of the skin barrier, lipids in general also prevent transepidermal water loss and offer protection against environmental stressors.

Formulation
Stability
Nacre lipids are characterized by their oil solubility, consistent with their extraction using a methanol/chloroform mixture. While general lipid nanoparticles (LNPs) have shown stability across a pH range of 3 to 9 at 2°C for over 156 days, specific optimal pH stability for Nacre Lipids has not been determined.
Safety
Safety Profile
No specific safety assessment for Nacre Lipids by CIR or SCCS has been identified. While a preclinical study on nacre powder (not lipids) indicated a moderate inflammatory response in an intraosseous sheep model, this finding is not directly applicable to the topical cosmetic use of Nacre Lipids.

Verdict
Nacre Lipids present a valuable, scientifically-supported mechanism for skin barrier repair and reconstitution, particularly beneficial for dry and sensitive skin. However, comprehensive safety and specific topical application concentration data are currently limited.
