The South China Beauty Peptide Production Factory, in conjunction with the Biological Research Laboratory, has completed the research and development of a composite repair peptide group, which scientifically combines anti-inflammatory peptides, barrier repair peptides, and moisturizing peptides to adapt to sensitive skin and post sun repair skincare products. The factory has established a large-scale production process for compound peptides, which can provide prefabricated compound raw liquid products, saving the cost of multiple ratio adjustments for the brand. Relying on its own synthesis workshop, the proportion of various peptides can be flexibly adjusted to adapt to multiple dosage forms such as water emulsion, spray, cold compress, etc. Once launched, this series of composite peptides has received numerous orders from sensitive skin care brands, expanding the application boundaries of beauty peptides in the repair field.
