From a molecular structure perspective, the absorption of collagen peptides follows two pathways—the amino acid pathway (which aids in synthesizing proteins required by the human body) and the peptide pathway (where short peptide fragments such as dipeptides and tripeptides are absorbed). The smallest unit of protein is amino acids, which form peptide chains through various combinations, and these peptide chains then constitute proteins. As a type of protein, collagen also follows this principle. Thus, not all collagen peptides are broken down into amino acids before being reassembled.
In terms of application scenarios, besides oral collagen peptide products, topical collagen peptides are divided into collagen peptide dressings and collagen peptide microneedles. Through microneedles, collagen peptides can penetrate the stratum corneum and reach the dermis layer. Collagen peptide dressings have also been proven to have a certain degree of absorption effect.
The general public lacks an in-depth understanding of collagen peptides and has limited channels to learn about their fundamental principles. Therefore, in addition to the main research and development planning of the project, we have also organized popular science lectures and installation exhibitions to address this.
