Copper peptides are quite beneficial for both skin and hair, as shown by clinical trials. They are often used in skin care lotions, creams and serums designed particularly for the purpose of reducing facial lines and wrinkles. What accounts for the prevalence of copper peptides is that: copper peptides can rejuvenate skin cells in aging tissue by boosting the production of collagen and elastin.
Levels of these structural proteins naturally decrease with age, that’s why we need to add them artificially in the tissue, so as to help skin regain elasticity and strength even at an older age. They were proved to be effective as many signs of aging are noticed to slow down after the use of copper peptides.
Definition of Copper Peptide
Copper Peptide is also referred to as GHK (glycyl-L-histidyl-L-lysine) peptide. It is present in human plasma, saliva, and urine but declines with age. It is proposed that GHK functions as a complex with copper 2+ which accelerates wound healing and skin repair. GHK stimulates both synthesis and breakdown of collagen and glycosaminoglycans and modulates the activity of both metalloproteinases and their inhibitors.
Benefits of Copper Peptide
- Clinical research has made it clear that copper peptides are antioxidants, nutrients that counteract the oxidizing effects of environmental particles called free radicals. It stimulates collagen, chondroitin sulfate, and the small proteoglycan as well as a string of other chemicals.
- Copper peptides also restores replicative vitality to fibroblasts after radiation therapy. The molecule attracts immune and endothelial cells to the site of an injury. It accelerates wound-healing of the skin, hair follicles, gastrointestinal tract, boney tissue, and foot pads of dogs. The same wound healing effects are also detected in rats, mice, and pigs.
- In cosmetic products, it has been found to tighten loose skin and improve elasticity, skin density, and firmness, reduce fine lines and wrinkles, reduce hyperpigmentation, and increase keratinocyte proliferation.
Therapeutic Use of Copper Peptide
Copper Peptide has been proposed as a therapeutic agent for skin inflammation, chronic obstructive pulmonary disease, and metastatic colon cancer. It is capable of up- and down-regulating at least 4,000 human genes, essentially resetting DNA to a healthier state.
Possible Side Effects of Copper Peptide
Despite the fact that copper peptides are commendable or its anti-aging benefits in skincare, one should still be careful with the dose they use daily. All things have two sides, positive and negative. Copper peptides are no exception. According to the Mayo Clinic, cosmetics and skincare products containing copper peptides may cause redness, burning sensation or the development of a rash, which is also clearly stated in the manufacturer's guidelines.
Except for skin irritation, overuse of copper peptides might also cause digestive tract disturbances and nervous system toxicity.
