Application
- L-carnosine is a natural antioxidant that presents in our body's muscles, brain, heart, and other parts.
- L-carnosine is applied in cosmetics and dietary supplement.
Antioxidant
Carnosine (CAS 305-84-0), a potent antioxidant, helps eliminate free radicals generated through cellular oxidation and inhibits the formation of Advanced Glycation End-products (AGEs).
Anti-aging and anti wrinkle:
Through multiple mechanisms including free radical scavenging, mitochondrial protection, and anti-glycation properties, this compound effectively delays skin aging processes.
Why Partner With Us? Our Core Competences
Ultra-High Purity (>99.5%)
Our advanced purification technology ensures an L-Carnosine purity of over 99.5%. Higher purity means fewer impurities, better solubility, and superior stability in your final cosmetic formulas (such as serums, creams, and lotions).
Strict Safety Standards (Heavy Metal Tested)
Skin safety is our priority. Every batch of our L-Carnosine undergoes rigorous third-party testing. We provide comprehensive Heavy Metal Test Reports and Certificates of Analysis (COA) to ensure 100% compliance with global cosmetic regulations.
Traceable Quality Control
From raw material sourcing to the final product, our manufacturing process operates under strict ISO/GMP-compliant quality management systems.
What Makes L-Carnosine Essential in Cosmetics?
Powerful Anti-Glycation:
Prevents the cross-linking of collagen and elastin, protecting the skin from structural damage caused by Advanced Glycation End-products (A.G.E.s).
Cellular Antioxidant:
Helps extend the lifespan of fibroblasts, promoting a firmer and more youthful complexion.
Skin Rejuvenation:
Neutralizes free radicals and reactive oxygen species (ROS), delaying signs of skin aging.
