Science
Mechanism of Action
Lactis Lipida seamlessly integrates into the skin's natural lipid matrix, predominantly within the stratum corneum, the outermost layer of the epidermis. This integration is pivotal for fortifying the skin barrier function, effectively preventing transepidermal water loss (TEWL) and offering protection against external aggressors. Furthermore, it contributes to the skin's intrinsic antimicrobial defense mechanisms.

Stability
While a specific optimal pH range for Lactis Lipida's stability is not precisely defined, its function as a skin lipid inherently supports the skin's natural pH equilibrium (typically between 4.0 and 6.5), which is vital for maintaining enzymatic functions and the integrity of the lamellar structure.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) identifies insufficient data for Lactis Lipida, and a specific Scientific Committee on Consumer Safety (SCCS) opinion is not available. Nevertheless, analogous ingredients such as 'Fatty Acids & Fatty Acid Salts' have been evaluated as safe for cosmetic applications. In the U.S., the FDA permits cosmetic ingredients (excluding color additives) without pre-market approval, provided they are safe under specified conditions of use. Lactis Lipida is not listed as prohibited or restricted by the FDA, and SkinSAFE categorizes it as 'Irritant Free', indicating a negligible risk of irritation.
