Manufacturing & Quality Control

The production of Korean silk peptide botox serum follows a multi-stage process that ensures batch-to-batch consistency and high purity. Manufacturing begins with solid-phase peptide synthesis (SPPS) using Fmoc chemistry, followed by cleavage and deprotection. The crude peptide is then purified via preparative HPLC to achieve the required 98%+ purity threshold.

Production Process

After synthesis, the peptide is conjugated with low-molecular-weight silk fibroin hydrolysate (500–2000 Da) through a controlled enzymatic reaction. This conjugation step enhances the peptide's stability and skin affinity. The final product is lyophilized or supplied as a sterile aqueous solution, depending on client specifications.

Purification & Testing

Each batch undergoes rigorous quality control testing, including reversed-phase HPLC for purity verification, mass spectrometry for molecular weight confirmation, and amino acid analysis for composition accuracy. Third-party laboratories perform independent validation of endotoxin levels, heavy metal content, and microbial limits.
