Science

Mechanism of Action

This ingredient functions by integrating into the skin's natural physiological processes. As a critical structural precursor for ceramides, Isomerized Linoleic Acid is integral to upholding the integrity and function of the epidermal barrier. Its demonstrated anti-inflammatory properties contribute to alleviating conditions such as acne, psoriasis, and neurodermatitis. Additionally, it aids in skin brightening by modulating melanin production and promoting the desquamation of pigmented cells from the upper epidermal layers.

Stability

As a highly lipophilic compound, Isomerized Linoleic Acid, along with its precursor, requires careful formulation. Elevated temperatures, exposure to oxygen, and alkaline pH conditions can enhance the isomerization process, potentially altering its desired isomeric profile and stability. Prudent control over these parameters is essential to preserve efficacy.
