Leucine
Ingredient Info
Leucine is an amino acid—a building block of proteins—that is sometimes included in skincare formulations. In topical products, it's primarily used as a skin-conditioning agent, though its direct effects on skin are limited compared to oral consumption.
Benefits
- May support skin barrier function as part of amino acid complexes
- Provides mild skin conditioning properties
Science: The provided research focuses on leucine's role in systemic nutrition and immune function (particularly in psoriasis management via diet), not topical skincare applications. Limited peer-reviewed data exists specifically demonstrating efficacy of leucine in cosmetic formulations applied to skin.
