Lactobacillus Ferment is a byproduct created when beneficial Lactobacillus bacteria are fermented and then processed. It's used in skincare for its potential to support skin balance and calm irritation, particularly in sensitive skin formulations.
Benefits
May help soothe sensitive or reactive skin
Supports a balanced skin microbiome
Can reduce sensations of scalp discomfort and sensitivity
Potential concerns
Limited effectiveness against certain microorganisms (notably Candida albicans in preservative testing)
Rare allergic reactions possible in sensitive individuals
Science: Research shows that Lactobacillus ferment complexes can meaningfully modulate scalp microbiome composition and alleviate sensitive scalp symptoms in clinical studies. However, peer-reviewed evidence is currently limited to specialized applications (scalp health), and broader efficacy data for general facial skincare remains sparse.
Tetrasodium Glutamate Diacetate is a chelating agent that binds to metal ions (like calcium and iron) in skincare formulations, preventing them from causing unwanted chemical reactions or product degradation. It helps keep products stable and effective over time.
Benefits
Stabilizes skincare formulations by controlling metal ion activity
Helps prevent product discoloration and oxidation
Allows products to maintain consistency and efficacy during storage
Science: The Cosmetic Ingredient Review Expert Panel concluded in 2025 that Tetrasodium Glutamate Diacetate is safe for use in cosmetics at typical concentrations. Research shows it functions effectively as a chelator, with strong binding capacity for metals like calcium and iron.
