Marine collagen peptides have the characteristics of small molecular weight, easy absorption, high bioavailability and good functional activity, and have been widely used in functional foods, biomedicine and cosmetics.
The skin protection effects of marine collagen peptides are explained from the aspects of anti-oxidation, whitening, anti-aging, anti-inflammation, and promotion of wound healing and tissue repair. The absorption and metabolism rules and safety characteristics of marine collagen peptides in the body are introduced, in order to provide theoretical support for the development and application of marine collagen peptides in marine functional cosmetics.
Efficacy:
1. Anti-oxidation
Imbalance of reactive oxygen free radicals in the body is a key factor causing skin aging. External environmental factors such as ultraviolet radiation and pollutants can cause excessive production of reactive oxygen free radicals in the skin and depletion of antioxidant enzymes in the body.
In addition, oxidative stress mediated by reactive oxygen free radicals can lead to lipid oxidation and DNA damage, triggering the expression of matrix metalloproteinases (MMPs). MMPs degrade extracellular matrix collagen and elastin, destroy the structure and integrity of the dermis, and thus lead to skin aging.
Current studies have shown that marine biological collagen peptides have the function of scavenging free radicals in vitro. For example, the research results of Chen Bei et al showed that the two-spot puffer fish skin collagen peptide with a molecular weight of less than 1 kul has the ability to scavenge free radicals; the cod fish bone collagen peptide has a better ability to scavenge DPPH than to scavenge superoxide anion free radicals .
2.Reduce the loss of skin collagen
Collagen is the main component of human skin. With the passage of time and the influence of the external environment, the decrease in collagen strength and thickness becomes the main factor of skin aging.
Hyp is the signature amino acid of collagen, and the decrease in Hyp content is one of the main signs of aging skin. Studies have shown that marine biological collagen peptides can significantly increase the content of Hyp, thereby promoting the synthesis of skin collagen. Pacific cod skin gelatin hydrolyzate can promote the synthesis of type I procollagen by upregulating transforming growth factor-β type II receptor. Collagen peptides extracted from cod skin reduce the content of MMP-1 by inhibiting the expression of phosphorylation of proteins related to the mitogen-activated protein kinase signaling pathway.
3. Anti-inflammatory activity
Skin problems such as peeling, redness, itching, and acne can mostly be attributed to skin inflammation.Inflammation is a defensive response of the human body and is usually beneficial, but if inflammation persists for a long time, it will lead to deterioration of skin conditions and damage to the skin barrier.
4.Promote wound healing ability and tissue repair function
Marine biological collagen and its hydrolyzate have good repair effects on skin damage exposed to ultraviolet light. Through in vitro cell experiments, researchers found that jellyfish and cod skin peptides can increase the content of cellular collagen and hyaluronic acid, and have a repair effect on damaged cells.
