Glutamic Acid
Ingredient Info
Glutamic acid is a naturally occurring amino acid that functions as a humectant in skincare, helping to draw moisture into the skin and support its natural hydration barrier. It's often used in the form of poly-γ-glutamic acid (γ-PGA), a biodegradable biopolymer derived from bacterial fermentation that enhances the moisturizing properties of skincare formulas.
Benefits
- Humectant that attracts and retains moisture in the skin
- Supports skin hydration and barrier function
- Biodegradable and generally well-tolerated by most skin types
Science: Poly-γ-glutamic acid is a well-documented, biodegradable biopolymer with good biocompatibility and non-toxic profile, widely used in cosmetic formulations. Research confirms it is safe and effective for moisture-binding applications in skincare.
