Collagen Peptides: Multiple Skin-Benefiting Effects Backed by Scientific Research
Enhance the Repair Function of Skin Fibroblasts
In cell culture experiments, embryonic skin fibroblasts treated with UV radiation and then cultured with different doses of collagen peptides showed significantly better morphological characteristics compared to the blank control group. Notably, their condition was close to that of the normal (untreated) group. This compelling evidence indicates that collagen peptides can significantly promote the synthesis of collagen type I and hyaluronic acid in fibroblasts, thereby exerting a powerful repair effect on damaged skin fibroblasts—a key factor in maintaining skin elasticity and integrity.
Boost Skin Moisture Content
Moisture level testing on the skin of various experimental mice revealed that all collagen peptide-treated groups exhibited significantly higher skin moisture content than the model group (damaged skin group). Furthermore, the medium and high-dose collagen peptide groups even achieved higher moisture levels than the control group. These findings confirm that collagen peptides are effective in replenishing and retaining moisture in damaged skin, addressing one of the most common skin concerns.
Inhibit Tyrosinase Activity
In vitro simulated digestion and tyrosinase activity inhibition assays demonstrated that collagen peptides possess excellent tyrosinase-inhibiting properties. Specifically, in vitro simulated gastrointestinal digestion further enhanced both the tyrosinase-inhibiting activity and antioxidant activity of collagen peptides. This dual enhancement highlights the potential of collagen peptides in supporting a more even skin tone by targeting melanin production.
Smaller and More Concentrated Molecular Weight
Gelken offers collagen peptides with various small molecular weights, including the highly sought-after 500-2000Da range. These peptides feature a rich amino acid composition, with particularly high levels of proline and hydroxyproline—two characteristic amino acids essential for collagen synthesis. Such superior specifications make Gelken's collagen peptides versatile for meeting diverse needs across the healthcare, beauty, and skincare industries.
