Product Introduction
Cosmetic Grade L-Theanine is a highly purified, ultra-stable amino acid derivative specifically optimized for premium topical skincare and advanced scalp care systems. Unlike standard dietary-grade alternatives that suffer from poor dermal bioavailability and complex formulation compatibility, our dedicated cosmetic-grade L-Theanine delivers superior skin-penetrating properties, profound cellular calming metrics, and outstanding antioxidant synergy.

Targeted Cosmetic Applications & Topical Benefits
1. Advanced Scalp & Hair Follicle Care Systems
Anti-Inflammatory Scalp Shield: Counteracts chemical stresses induced by hair dyes, styling polymers, and surfactants. Markedly reduces erythema and itching.
Follicle Energizer: Regulates local cortisol/stress pathing on the scalp to inhibit stress-related thinning and preserve healthy growth cycles.
Sebum Control: Balances oily scalps without stripping the natural moisture barrier.
2. Anti-Stress & Neuro-Calming Skincare
Glutamate Receptor Antagonism: Effectively modulates topical neurological stress markers, mitigating sensory irritation and redness in sensitive skin types.
Cortisol Suppression: Dampens environmental micro-stress signals to halt collagen degradation caused by stress-induced matrix metalloproteinases (MMPs).
3. Skin Barrier Reconstruction & Deep Hydration
Filaggrin Upregulation: Stimulates tight-junction proteins and filaggrin synthesis, accelerating cellular recovery after chemical peeling or environmental damage.
Formulation & Compounding Guidelines
Recommended Usage Level: 0.5% – 3.0% for face creams, hydrogels, and essences; 1.0% – 5.0% for specialized scalp therapy treatments.
Optimum pH Stability Range: Extremely stable between pH 4.5 and 7.5. Compatible with non-ionic, anionic, and cationic emulsifier matrix networks.
Processing Rule: Highly water-soluble. It is recommended to dissolve L-Theanine in the aqueous phase. Avoid prolonged heating above 80°C to preserve long-term amino acid structural integrity.
