Manufactured and supplied directly by PEPDOO® — your global source for clinically supported B2B peptide solutions.
Patented Mulberry Leaf Peptide: Proven Skin Brightening & Oral Bioavailability
- Inhibits Tyrosinase Activity by up to 76.7%
- <1000Da Peptide Fraction for High Bioavailability
- Supports Skin Brightening via Melanin Suppression
- Enhanced Stability after Gastrointestinal Digestion
- Ideal for Oral Beauty-from-Within Formulations
Our Proprietary Dual-Enzyme Hydrolysis Patent Technology
PEPDOO® holds the exclusive Chinese patent (CN 115970182 A) for a proprietary dual-enzyme hydrolysis extraction method, enabling the efficient production of mulberry leaf peptides with molecular weight under 1000 Da.
This advanced process achieves a remarkable 76.7% inhibition of tyrosinase activity at just 2% peptide concentration, significantly outperforming traditional mulberry polyphenols and flavonoids in skin-brightening efficacy.
By combining amide enzyme pre-treatment with neutral and acidic protease hydrolysis, our method ensures high yield, superior bioavailability, and consistent peptide quality.
