TongRen Peptide specializes in the custom synthesis and production of cosmetic-grade peptides for skincare and personal care formulators. Our facility focuses on a wide range of popular beauty peptides, including signal peptides, anti-aging peptides, brightening peptides and barrier-repair peptides.

We implement rigorous quality control throughout synthesis, purification and lyophilization. Each batch undergoes HPLC and mass spectrometry testing to confirm purity and consistency, with complete COA documents available. Our technical team supports custom sequence adjustment, small trial batches and bulk orders to match different formulation needs.

We follow stable production standards to reduce impurities and maintain peptide activity. Our peptide materials serve cosmetic brands, R&D labs and formulators worldwide. All raw peptide supplies are intended for cosmetic formulation use only, not for direct injection or medical application.
